Function/Subroutine Documentation

computeinverseroot()

subroutine, public rootsolversmodule::computeinverseroot	(	type(distributedsparsematrix_t), intent(in)	InputMat,
		type(distributedsparsematrix_t), intent(inout)	OutputMat,
		integer, intent(in)	root,
		type(iterativesolverparameters_t), intent(in), optional	solver_parameters_in
	)

Compute a general inverse matrix root.

Parameters

[in]	InputMat	the input matrix
[out]	OutputMat	= InputMat^-1/root.
[in]	root	which root to compute.
[in]	solver_parameters_in	parameters for the solver (optional).

Todo:

the inverse cube root.
