solve_linear_system_complex_banded_LU Function

public function solve_linear_system_complex_banded_LU(bandmatrix, vector, LU, ipiv) result(xvector)

Calculates the solution $X$ to a system of linear equations $AX = B$ where $A$ is a complex banded matrix and $B$ is a complex vector. Uses the LU factorisation of $A$ and pivoting information from zgbtrf.

Arguments

Type	Intent	Optional	Attributes		Name
type(banded_matrix_t),	intent(in)			::	bandmatrix	the banded $A$-matrix on the left-hand side
complex(kind=dp),	intent(in)			::	vector(:)	the $B$-vector on the right-hand side
complex(kind=dp),	intent(in)			::	LU(:,:)	the LU factorisation of $A$, from zgbtrf
integer,	intent(in)			::	ipiv(:)	the pivoting information from zgbtrf

Return Value complex(kind=dp)(size(vector))

the solution vector $X$
