could tell me, can find source code matrix multiplication realized openfoam, petsc or similar? can't trivial algorithm. have found homepages of openfoam , petsc in doc cant find multiply methods , source code.

petsc implements matrix multiplication many formats, @ part of matmult_seqaij basic implementation. sparse matrix stored in compressed sparse row form row starts ai, column indices aj, , entries aa, multiplication consists of following simple kernel.

for (i=0; i<m; i++) {   y[i] = 0;   (j=ai[i]; j<ai[i+1]; j++)     y[i] += aa[j] * x[aj[j]]; }
