-More efficient and still quite simple method for the arrays initiation is with the use of C++ lambda functions and method `evaluate`. This method is implemented in `ArrayView` only. As an argument a lambda function is passed which is then evaluated for all elements. Optionally one may define only subinterval of element indexes where the lambda shall be evaluated. If the underlying array is allocated on GPU, the lambda function is called from CUDA kernel. This is why it is more efficient than use of `setElement`. On the other hand, one must be careful to use only `__cuda_callable__` methods inside the lambda. The use of the method `evaluate` demonstrates the following example.

4. **Methods `setElement` and `addElement` called on the host and copy matrix on GPU** setting particular matrix elements by the methods `setElement` and `addElement` when the matrix is allocated on GPU can be time consuming for large matrices. Setting up the matrix on CPU using the same methods and copying it on GPU at once when the setup is finished can be significantly more efficient. A drawback is that we need to allocate temporarily whole matrix on CPU.
5. **Methods `setElement` and `addElement` called from native device** allow to do efficient matrix elements setup even on devices (GPUs). In this case, the methods must be called from a GPU kernel or a lambda function combined with the parallel for (\ref TNL::Algorithms::ParallelFor). The user get very good performance even when manipulating matrix allocated on GPU. On the other hand, only data structures allocated on GPUs can be accessed from the kernel or lambda function. The matrix can be accessed in the GPU kernel or lambda function by means of [matrix view](#matrix_view) or the shared pointer (\ref TNL::Pointers::SharedPointer).
6. **Method `getRow` combined with `ParallelFor`** is very similar to the previous one. The difference is that we first fetch helper object called *matrix row* which is linked to particular matrix row. Using methods of this object, one may change the matrix elements in given matrix row. An advantage is that the access to the matrix row is resolved only once for all elements in the row. In some more sophisticated sparse matrix formats, this can be nontrivial operation and this approach may slightly improve the performance. Another advantage for sparse matrices is that we access the matrix elements based on their *local index* ('localIdx', see [Indexing of nonzero matrix elements in sparse matrices](indexing_of_nonzero_matrix_elements_in_sparse_matrices)) in the row which is something like a rank of the nonzero element in the row. This is more efficient than addressing the matrix elements by the column indexes which requires searching in the matrix row. So this may significantly improve the performance of setup of sparse matrices. When it comes to dense matrices, there should not be great difference in performance compared to use of the methods `setElement` and `getElement`. Note that when the method is called from a GPU kernel or a lambda function, only data structures allocated on GPU can be accessed and the matrix must be made accessible by the means of matrix view.

* **setElement on host and copy** tests are, similar to the dense matrix, much faster compared to the previous approaches. So it is the best way when you need to use data structures available only on the host system (CPU).

-Here we see, that the `setElement` methods performs extremely bad because all matrix elements are transferred to GPU one-by-one. Even STL map is much faster.

Setup of the matrix on CPU by the means of `setElement` method and transfer on GPU is even faster. However, the best performance can be obtained only we creating the matrix directly on GPU by methods `setElement`, `getRow` and `forRows`. Note, however, that even if all of them perform the same way, for matrices with more nonzero matrix elements in a row, `setElement` could be slower compared to the `getRow` and `forRows`.

+#### Symmetric sparse matrices
+
+For sparse [symmetric matrices](https://en.wikipedia.org/wiki/Symmetric_matrix), TNL offers a format storing only a half of the matrix elements. More precisely, ony the matrix diagonal and the elements bellow are stored in the memory. The matrix elements above the diagonal are deduced from those bellow. If such a symmetric format is used on GPU, atomic operations must be used in some matrix operations. For this reason, symmetric matrices can be combined only with matrix elements values expressed in `float` or `double` type. An advantage of the symmetric formats is lower memory consumption. Since less data need to be transferred from the memory, better performance might be observed. In some cases, however, the use of atomic operations on GPU may cause performance drop. Mostly we can see approximately the same performance compared to general formats but we can profit from lower memory requirements which is appreciated especially on GPU. The following example shows how to create symmetric sparse matrix.
+
+\includelineno SymmetricSparseMatrixExample.cpp
+
+We construct matrix of the following form

+\f[

+ 1 & \color{grey}{2} & \color{grey}{3} & \color{grey}{4} & \color{grey}{5} \\

+ 3 & & 1 & & \\
+ 4 & & & 1 & \\
+ 5 & & & & 1
+\end{array}
+\right)
+\f]
+
+The elements depicted in grey color are not stored in the memory. The main difference, compared to creation of general sparse matrix, is on line 9 where we state that the matrix is symmetric by setting the matrix type to \ref TNL::Matrices::SymmetricMatrix. Next we set only the diagonal elements and those lying bellow the diagonal (lines 13-17). When we print the matrix (line 19) we can see also the symmetric part above the diagonal. Next we test product of matrix and vector (lines 21-23). The result looks as follows:
+
+\include SymmetricSparseMatrixExample.out
+
+**Warning: Assignment of symmetric sparse matrix to general sparse matrix does not give correct result, currently. Only the diagonal and the lower part of the matrix is assigned.**
+
+#### Binary sparse matrices
+
+If the matrix element value type (i.e. `Real` type) is set to `bool` the matrix elements can be only `1` or `0`. So in the sparse matrix formats, where we do not store the zero matrix elements, explicitly stored elements can have only one possible value which is `1`. Therefore we do not need to store the values, only the positions of the nonzero elements. The array `values`, which usualy stores the matrix elements values, can be completely omitted and we can reduce the memory requirements. The following table shows how much we can reduce the memory consumption when using binary matrix instead of common sparse matrix using `float` or `double` types:
+
+| Real | Index | Common sparse matrix | Binary sparse matrix | Ratio |
+|:------:|:------:|:--------------------:|:--------------------:|:----------:|
+| float | 32-bit | 4 + 4 = 8 B | 4 B | 50% |
+| float | 64-bit | 4 + 8 = 12 B | 8 B | 75% |
+| double | 32-bit | 8 + 4 = 12 B | 4 B | 33% |
+| double | 64-bit | 8 + 8 = 16 B | 8 B | 50% |
+
+The following example demonstrates the use of binary matrix:
+
+\includelineno BinarySparseMatrixExample.cpp
+
+All we need to do is set the `Real` type to `bool` as we can see on the line 9. We can see that even though we set different values to different matrix elements (lines 14-18) at the end all of them are turned into ones (printing of the matrix on the line 20). There is an issue, however, which is demonstrated on the product of the matrix with a vector. Nonbinary matrices compute all operations using the `Real` type. If it is set to `bool` operations like [SpMV](https://en.wikipedia.org/wiki/Sparse_matrix-vector_multiplication) would not get correct solution. Therefore sparse matrices use another type called `ComputeReal` which is the 6th template parameter of \ref TNL::Matrices::SparseMatrix. By default it is set to `Index` type but it can be changed by the user. On the lines 26-29 we show how to change this type to `double` and what is the effect of it (correct result of matrix-vector multiplication). The result looks as follows:

+TNL also offers matrix reader (\ref TNL::Matrices::MatrixReader) and matrix writer (\ref TNL::Matrices::MatrixWriter) for import and export of matrices respectively. The matrix reader currently supports only [Coordinate MTX file format](https://math.nist.gov/MatrixMarket/formats.html#coord) which is popular mainly for sparse matrices. By the mean of the matrix writer, we can export TNL matrices into coordinate MTX format as well. In addition, the matrices can be exported to a text file suitable for [Gnuplot program](http://www.gnuplot.info/) which can be used for matrix visualization. Finally, a pattern of nonzero matrix elements can be visualized via the EPS format - [Encapsulated PostScript](https://en.wikipedia.org/wiki/Encapsulated_PostScript).
