File: psb_dspins.f90 ! ! Subroutine: psb_dspins ! Takes a cloud of coefficients and inserts them into a sparse matrix. ! Note: coefficients with a row index not belonging to the current process are ! ignored. ! If desc_a is in the build state this routine implies a call to psb_cdins. ! ! Arguments: ! nz - integer. The number of points to insert. ! ia(:) - integer The row indices of the coefficients. ! ja(:) - integer The column indices of the coefficients. ! val(:) - real The values of the coefficients to be inserted. ! a - type(psb_dspmat_type). The sparse destination matrix. ! desc_a - type(psb_desc_type). The communication descriptor. ! info - integer. Error code ! rebuild - logical Allows to reopen a matrix under ! certain circumstances. ! subroutine psb_dspins(nz,ia,ja,val,a,desc_a,info,rebuild) use psb_base_mod, psb_protect_name => psb_dspins
