File: psb_dspins.f90 ! ! Subroutine: psb_dspins ! Takes a cloud of points and inserts them into a sparse matrix. ! ! Parameters: ! nz - integer. The number of points to insert. ! ia - integer,dimension(:). The row indices of the points. ! ja - integer,dimension(:). The column indices of the points. ! val - real,dimension(:). The values of the points to be inserted. ! a - type(). The sparse destination matrix. ! desc_a - type(). The communication descriptor. ! info - integer.
