Hi Jason,

why do you need different variable names? I would put the matrices in a 

function q[i].

Scan[q[i]=f[i],{i,1,40}]

I'd like to be able to define them all without writing out n assignment lines, so a Do loop seems appropriate to me but I don't know how to assign sequential variable names. This gets the job done but it is really ugly IMO
