mtx_inverse Interface

public interface mtx_inverse

Module Procedures

private subroutine mtx_inverse_dbl(a, iwork, work, olwork, err)

Computes the inverse of a square matrix.

Arguments

Type	Intent	Optional	Attributes		Name
real(kind=real64),	intent(inout),		dimension(:,:)	::	a	On input, the N-by-N matrix to invert. On output, the inverted matrix.
integer(kind=int32),	intent(out),	optional,	target, dimension(:)	::	iwork	An optional N-element integer workspace array.
real(kind=real64),	intent(out),	optional,	target, dimension(:)	::	work	An optional input, that if provided, prevents any local memory allocation. If not provided, the memory required is allocated within. If provided, the length of the array must be at least olwork.
integer(kind=int32),	intent(out),	optional		::	olwork	An optional output used to determine workspace size. If supplied, the routine determines the optimal size for work, and returns without performing any actual calculations.
class(errors),	intent(inout),	optional,	target	::	err	The error object to be updated.

private subroutine mtx_inverse_cmplx(a, iwork, work, olwork, err)

Computes the inverse of a square matrix.

complex(kind=real64),	intent(out),	optional,	target, dimension(:)	::	work	An optional input, that if provided, prevents any local memory allocation. If not provided, the memory required is allocated within. If provided, the length of the array must be at least olwork.
integer(kind=int32),	intent(out),	optional		::	olwork	An optional output used to determine workspace size. If supplied, the routine determines the optimal size for work, and returns without performing any actual calculations.
class(errors),	intent(inout),	optional,	target	::	err	The error object to be updated.
