# span of matrices over finite fields

Hello,

I'd to build the span of some matrices defined over GF(4). However, the function span doesn't fit since it seems to interpret matrices as lists of vectors. I tried the following :

```
F=GF(4);
n=11;
A=random_matrix(F,n);
B=random_matrix(F,n);
print(span(A,F));
print(span([A,B],F));
```

None of which gives satisfying results (the second one gives an error). So, I wanted to know if there was a way to properly get a span of matrices in sagemath.

Thanks in advance.
