File: psb_dcoins.f90 ! Subroutine: psb_dcoins ! Takes a cloud of coefficients and inserts them into a sparse matrix. ! This subroutine is the serial, inner counterpart to the outer, user-level ! psb_spins. ! ! Arguments: ! ! nz - integer, input The number of points to insert. ! ia(:) - integer, input The row indices of the coefficients. ! ja(:) - integer, input The column indices of the coefficients. ! val(:) - real, input The values of the coefficients to be inserted. ! a - type(psb_dspmat_type), inout The sparse destination matrix. ! imin - integer, input The minimum valid row index ! imax - integer, input The maximum valid row index ! jmin - integer, input The minimum valid col index ! jmax - integer, input The maximum valid col index ! info - integer, output Return code. ! gtl(:) - integer, input,optional An index mapping to be applied ! default: identity ! rebuild - logical, input, optional Rebuild in case of update ! finding a new index.
