Expression is too large for MATLAB to evaluate

Hello everybody, I have a 6x36 symbolic matrix and I wanted to make it a function handle with function matlabFunction. I need to do this because later on I need to evaluate this 6x36 matrix numerically and I've noticed that numerical substitution with function feval is much faster than function subs. Unluckily when I use matlabFunction with the matrix in input I obtain this errore code:
Error using symengine
Error: Expression is too large for MATLAB to evaluate.
Error in symengine
Error in sym/matlabFunction (line 190)
g = symengine('makeFhandle',varnames,body);
I've also tried to simplify the symbolic matrix with the opportune function but the result was the MATLAB crashed twitce. I'm open to other suggestion on how evaluate numerically a symbolic matrix.
