Finding the determinant of a variable matrix in MATLAB
I'm a bit new to MATLAB so this should be a simple question for someone with
experience. I'm trying to find the determinant of a matrix with variables,
A = [x 2*l; 3 4] where x is a variable and l is a constant. Then I want to s
et it to equal zero (det(A)=0) and I want the answer to be in a simplified v
ersion. So in this case I would like it to return 2x -3l = 0.
How exactly do I do this in MATLAB?

one of the solutions might look like this (requires the
<sym math tbx> )...
% the matrix
a=sym('[x 2*l; 3 4]');
% ad = 4*x-6*l
