invalid conversion from ‘int’ to ‘Array<int>**

I'm getting the above error pointing at my initlist in Matrix and I can't seem to figure out why. It definitely has something to do with the way I defined m. For some context, m is supposed to be an array of array pointers using Array.h.

Anyone? I'm still spinning my wheels here seeing if it could be my array header or something syntactically wrong with the way I'm defining my template
