If you do check that if you have the Octave-forge comms toolbox 
installed something like

m = 2;
n = 2.^m;
a = gf (floor(randn(10,10,n), m);
b = tril (a)

resize is used in tril and is used so that metadata in the input matrix 
(for the galois field about the primitive polynomial of the field), is 
preserved during the operation.
