This is my first post and I'm pretty much lost when it comes to linear algebra. I am a programmer and I am currently working on converting a 3D model format for personal purposes. I am having trouble figuring out an equation. If you want the background of what I am doing I'll be happy to explain but it really isn't necessary to solve my problem.(adsbygoogle = window.adsbygoogle || []).push({});

Lets say that I have two matrices (4x4) M1 and M2. One vector4 v. I transform v by M1 to get v1 and v by M2 to get v2. So...

M1 * v = v1

M2 * v = v2

I am looking for some matrix X.

X * v1 = v2, solve for X.

What I came up with is X = (M2 * v) / (M1 * v), cross out v and get X = M2 / M1 or X = M2 * M1_inverse.

This does not produce the result I am looking for. Any suggestions? Thank you for any help.
