Rmumps__ptr_ijv function

Construct via Triplet Pointers

This is a C wrapper to Rmumps::Rmumps(i, j, v, n, nz, sym) constructor. Available in R too. In C++ code can be used as rmumps::Rmumps__ptr_ijv(pi, pj, pa, n, nz, sym)

Rmumps__ptr_ijv(pi, pj, pa, n, nz, sym)

Arguments

• pi: pointer of type XPtr, vector of i-indeces for sparse triplet
• pj: pointer of type XPtr, vector of j-indeces for sparse triplet
• pa: pointer of type XPtr, vector or values for sparse triplet
• n: integer, size of the matrix (n x n)
• nz: integer, number of non zeros in the matrix
• sym: integer, 0 means general (non symmetric) matrix, 1 - symmetric with pivotes on the main diagonal, 2 - general symmetric (pivotes may be anywhere)

Returns

pointer of type XPtr pointing to newly created object. To avoid memory leakage, it is user's responsibility to call Rmumps__del_ptr(pm) in a due moment (where pm is the returned pointer).
