Member Function/Subroutine Documentation

cstransformmat()

subroutine matextensionmodule::cstransform::cstransformmat ( type(sysmatrixtype), intent(inout)  aMat, real(dp), dimension(:,:), intent(in)  tMat, real(dp), dimension(:,:), intent(out)  bMat, integer, intent(out)  ierr  )

private

Performs a triple matrix multiplication.

Parameters

[in]	aMat	System matrix A
[in]	tMat	Transformation matrix T
[out]	bMat	Resulting matrix B
[out]	ierr	Error flag

The matrix multiplication B = T ^T A T is performed, where A is on compact (sparse) form and T is a dense rectangular matrix.

cstransformvec()

subroutine matextensionmodule::cstransform::cstransformvec ( type(sysmatrixtype), intent(inout)  aMat, real(dp), dimension(:), intent(in), target  v, real(dp), intent(out)  bVal, integer, intent(out)  ierr  )

private

Performs a vector-matrix-vector multiplication.

Parameters

[in]	aMat	System matrix A
[in]	v	System vector
[out]	bVal	Resulting value
[out]	ierr	Error flag

The multiplication b = v ^T A v is performed, where A is on compact (sparse) form and v is a vector. The result b is s scalar quantity.
