# Should I use mantel test to test for signifance between [nxm] matrices?

I was looking into the Mantel test, but I'm worried that I was going to get myself into a pitfall.

I read that it would be erronous to use a mantel test for datasets spatial auto-correlation, and I'm not sure if my dataset (I've included an image) falls into this category.

Essetially, what I'm trying to do is to decompose my matrix into vectors which I can multiply together to retrive an analog to the 2d matrix. I want to apply a test to show that there is no significant difference between the original matrix and the matrix that I got from the vector multiplication.

Would the Mantel test show that, or would it be erronous? If so, what test should I apply to test for significance between matrices.

Thanks in advnace!
