Hi!(adsbygoogle = window.adsbygoogle || []).push({});

I have two sets of matrices where only the sign of each field might differ. I'm trying to calculate a generally applicable matrix that transforms the signs of the source matrix so it has the same signs like the target matrix. I tried calculating the inverse of the target matrix and multiply that with the source, but I'm missing a step. Maybe you guys can help!

Thanks a lot!!
