* *use scalar instructions, packet not needed hereGravatar Benoit Jacob2009-12-14
| | | | *remove unused var warning
* add SSE path for Matrix4f inverse, taken from Intel except that we do a kosherGravatar Benoit Jacob2009-12-14
| | | | | | division instead of RCPPS-followed-by-Newton-Raphson. The rationale for that is that elsewhere in Eigen we dont allow ourselves this approximation (which throws 2 bits of mantissa), so there's no reason we should allow it here.
* * 4x4 inverse: revert to cofactors methodGravatar Benoit Jacob2009-12-09
| | | | | | | * inverse tests: use createRandomMatrixOfRank, use more strict precision * tests: createRandomMatrixOfRank: support 1x1 matrices * determinant: nest the xpr * Minor: add comment
