Hello. I've got a huge 6x6 symbolic matrix M that can't be just pasted/inlined on a function to substitute values because of its size. I've had some bad experiences with the function subs(), being extremely slow. The recommended alternative is to convert the symbolic expression into a Matlab Function through matlabFunction() and then substitute from it. Given that, I tried:
M = % Huge sym 6x6 matrix
for i = 1:6
for j = 1:6
fM{i,j} = matlabFunction(M(i,j));
end
end
Which throws:
Unable to perform assignment because brace indexing is not supported for variables of this type.
I tried many variants but none of them worked. I feel like I'm very far from the solution, if there's any.
Thank you,
Jose
