template<typename MT , bool SO>
Returns the current capacity of the specified row/column.
- Parameters
-
matrix | The given matrix. |
i | The index of the row/column. |
- Returns
- The current capacity of row/column i.
This function returns the current capacity of the specified row/column. In case the storage order is set to rowMajor the function returns the capacity of row i, in case the storage flag is set to columnMajor the function returns the capacity of column i.
template<typename MT , bool SO>
In-place conjugate transpose of the given matrix.
- Parameters
-
matrix | The given matrix to be transposed. |
- Returns
- void
- Exceptions
-
std::logic_error | Matrix cannot be transposed. |
This function transposes the given matrix in-place. The function fails if ...
- ... the given matrix has a fixed size and is non-square;
- ... the given matrix is a triangular matrix;
- ... the given submatrix affects the restricted parts of a triangular matrix;
- ... the given submatrix would cause non-deterministic results in a symmetric/Hermitian matrix.
In all failure cases a std::logic_error exception is thrown.
template<typename MT1 , bool SO1, typename MT2 , bool SO2>
Returns whether the two given matrices represent the same observable state.
- Parameters
-
a | The first matrix to be tested for its state. |
b | The second matrix to be tested for its state. |
- Returns
- true in case the two matrices share a state, false otherwise.
The isSame function provides an abstract interface for testing if the two given matrices represent the same observable state. This happens for instance in case a
and b
refer to the same matrix or in case a
and b
are aliases for the same matrix. In case both matrices represent the same observable state, the function returns true, other it returns false.
MatrixType mat1( 4UL, 5UL );

SubmatrixType sub1 =
submatrix( mat1, 0UL, 0UL, 4UL, 5UL );
SubmatrixType sub2 =
submatrix( mat1, 1UL, 1UL, 2UL, 3UL );
SubmatrixType sub3 =
submatrix( mat1, 1UL, 1UL, 2UL, 3UL );
template<typename MT , bool SO>
Returns the number of non-zero elements in the specified row/column.
- Parameters
-
matrix | The given matrix. |
i | The index of the row/column. |
- Returns
- The number of non-zero elements of row/column i.
This function returns the current number of non-zero elements in the specified row/column. In case the storage order is set to rowMajor the function returns the number of non-zero elements in row i, in case the storage flag is set to columnMajor the function returns the number of non-zero elements in column i.
template<typename MT , bool SO>
Changing the size of the matrix.
- Parameters
-
matrix | The given matrix to be resized. |
m | The new number of rows of the matrix. |
n | The new number of columns of the matrix. |
preserve | true if the old values of the matrix should be preserved, false if not. |
- Returns
- void
- Exceptions
-
std::invalid_argument | Invalid resize arguments for square matrix. |
std::invalid_argument | Matrix cannot be resized. |
This function provides a unified interface to resize dense and sparse matrices. In contrast to the resize()
member function, which is only available on resizable matrix types, this function can be used on both resizable and non-resizable matrices. In case the given matrix of type MT is resizable (i.e. provides a resize
function) the type-specific resize()
member function is called. Depending on the type MT, this may result in the allocation of new dynamic memory and the invalidation of existing views (submatrices, rows, columns, ...). Note that in case the matrix is a compile time square matrix (as for instance the blaze::SymmetricMatrix adaptor, ...) the specified number of rows must be identical to the number of columns. Otherwise a std::invalid_argument exception is thrown. If the matrix type MT is non-resizable (i.e. does not provide a resize()
function) and if the specified number of rows and columns is not identical to the current number of rows and columns of the matrix, a std::invalid_argument exception is thrown.
template<typename MT , bool SO>
In-place transpose of the given matrix.
- Parameters
-
matrix | The given matrix to be transposed. |
- Returns
- void
- Exceptions
-
std::logic_error | Matrix cannot be transposed. |
This function transposes the given matrix in-place. The function fails if ...
- ... the given matrix has a fixed size and is non-square;
- ... the given matrix is a triangular matrix;
- ... the given submatrix affects the restricted parts of a triangular matrix;
- ... the given submatrix would cause non-deterministic results in a symmetric/Hermitian matrix.
In all failure cases a std::logic_error exception is thrown.
