This fixes the warning appearing with GCC 10.2:
../../src/lib/matrix/matrix/Matrix.hpp:481:34: error: logical ‘and’ of equal expressions [-Werror=logical-op]
481 | for (size_t i = 0; i < M && i < N; i++) {
|
I would prefered something with if constexpr but we don't have that yet
in because we're using C++14.
