rmumps (version 5.2.1-36)

Rmumps__ptr_ijv: Construct via Triplet Pointers

Description

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)

Usage

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

Value

pointer of type XPtr<Rmumps> 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).

Arguments

pi

pointer of type XPtr<int>, vector of i-indeces for sparse triplet

pj

pointer of type XPtr<int>, vector of j-indeces for sparse triplet

pa

pointer of type XPtr<double>, 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)
