please guide me how to find the det of this 24*24 order symbolic matrix, it is showing that 25000 word limit is exceeded.

M=[A1 A2 A3 A4;B1 B2 B3 B4;C1 C2 C3 C4;D1 D2 D3 D4]; f= det(M);

May I ask what you need this determinant for ?

Sir, I am working on higher order Galerkin technique.

There is no way that you will be able to find the symbolic determinant of a 25 x 25 matrix unless nearly all of it is 0. It would have over 10^25 terms, each of which is going to be complicated.

You could instead try to use something like fsolve() of the det() of a purely numeric matrix

Thanks sir I will try this. Thanks a lot for responding.
