2017-05-08 23:35:49 -0600 | asked a question | Different result with fixed size matrices vs dynamic When multiplying small matrices, I get different results when using a 2x3 fixed sized matrix than a dynamic Mat_<float>. Is this really expected? I'm using 3.2, compiling with Clang++ and -O3, but GCC 5.4 returns the same error. More results: Doing these operations with Eigen 3.3, the results are the same as with the fixed sized matrices. Using Octave with double precision, the results are very close to the dynamic matrix's result. It looks like the dynamic matrices use |
