integer matrix

C · 3 functions · 4 lanes · 12 of 12 function-lanes behave identically

All 4 lanes recompile and return the same results as the original.

Dense integer matrix multiply, transpose, and a 3x3 determinant. The multiply is the canonical triple loop with two different strides, and the determinant is a flat expression over nine indexed loads.
