IMO the inlining of MATMUL should be restricted to small matrices (less than 4x4, 9x9 or 16x16 depending of your field!-). I have a variant of the polyhedron test induct.f90 in which I have replaced three dot products by the equivalent matmul and which executes ten times slower than the original test. Dominique
