Member Function/Subroutine Documentation

subroutine matextensionmodule::csgetsub12::csgetsub12dense	(	type(sysmatrixtype), intent(inout)	sysMat,
		integer, dimension(:), intent(in)	meqn1,
		integer, dimension(:), intent(in)	meqn2,

Extracts the 12 sub-matrix from a system matrix.

Parameters

[in]	sysMat	The system matrix to extract the sub-matrix from
[in]	meqn1	Matrix of status 1 equation numbers
[in]	meqn2	Matrix of status 2 equation numbers
[out]	subMat12	Extracted sub-matrix
[out]	ierr	Error flag

The system matrix sysMat is stored on compact (sparse) form, but is logically composed of four submatrices, like

    sysMat = | sub11 sub12 |
             | sub21 sub22 |

The sub-matrix sub12 is returned as a dense rectangular matrix.

subroutine matextensionmodule::csgetsub12::csgetsub12sparse	(	type(sysmatrixtype), intent(inout)	sysMat,
		type(sparsematrixtype), intent(out)	subMat12,
		integer, intent(out)	ierr
	)

private

Extracts the 12 sub-matrix from a system matrix.

Parameters

[in]	sysMat	The system matrix to extract the sub-matrix from
[out]	subMat12	Extracted sub-matrix
[out]	ierr	Error flag

The system matrix sysMat is stored on compact (sparse) form, but is logically composed of four submatrices, like

    sysMat = | sub11 sub12 |
             | sub21 sub22 |

The sub-matrix sub12 is returned as a sparse matrix.
