why not, you can use Convs for this they can easily handle square matrix

You don't need to use matrices for this task; you can flatten them into 4-element vectors and then reshape the output into a matrix.

Disclaimer: Im a noob at ML. This is all just some random thoughts of mine. Maybe you could try predicting the differences instead? For example predict a, a-b and a-d. Then use something like ReLU on the differences. I dont know how to deal with c as you have to ensure that it is <= both b and d. I was thinking of predicting both b-c and b-d but this may cause problems as there would be 2 equations of c giving different answers. I thought of just taking the min but it seems very sketchy. If only there were an additional constraint of b>=d lol

in order to enforce these dependencies you can 1) use additional loss elements to penalize network for breaking constraints 2) predict output in a sequential fashion, starting from the smallest element c, then predict differences with other elements and use max(diff, 0)
