ncols, cols | - the number of nonzeros and their columns Many br | |
vals | - if nonzero the column values Many br |
This routine zeros out ncols, cols, and vals. This is to prevent accidental Many brus of the array after it has been restored. If you pass NULL, it will Many brnot zero the pointers. Use of cols or vals after MatRestoreRow is invalid. Many br
MatRestoreRow(matrix,row,ncols,cols,values,ierr) Mat matrix (input) integer row (input) integer ncols (output) integer cols(maxcols) (output) double precision (or double complex) values(maxcols) outputMany brWhere maxcols >= maximum nonzeros in any row of the matrix. Many br
In Fortran MatRestoreRow() MUST be called after MatGetRow() Many brbefore another call to MatGetRow() can be made. Many br
