public subroutine brn_calc_bdw(mob, bdw, ierr, lconv, f)

Main driver routine for calculating B.dW.

Arguments

Type IntentOptional AttributesName
real(kind=rp), intent(inout), dimension(:,:):: mob

(sizm,sizm) symmetric positive definite matrix. On entry, contains the mobility matrix. On return, if meth = 'CHOL', the upper triangular part is overwritten with the result of Cholesky decomposition. The strictly lower triangular part is left intact.
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.
integer, intent(out) :: ierr

Error flag.
logical, intent(out), optional :: lconv

If meth = 'LANC', returns true if converged, false otherwise.
integer, intent(out), optional :: f

If meth = 'LANC', the number of iterations performed.
