calc_bdw_blanc Subroutine

private subroutine calc_bdw_blanc(mob, bdw, lconv, f, ierr)

Implements block Lanczos algorithm for calculating B.dW.

Arguments

Type IntentOptional Attributes Name
real(kind=rp), intent(in), dimension(:,:) :: mob

(sizm,sizm) symmetric positive definite matrix.
real(kind=rp), intent(inout), dimension(:,:) :: bdw

(sizm,s) matrix. On entry, contains s column vectors drawn from standard normal distribution. On return, the s columns are overwritten with the result of B.dW.
logical, intent(out) :: lconv

Returns true if converged, false otherwise.
integer, intent(out) :: f

The number of iterations performed.
integer, intent(out) :: ierr

Error flag.
