This in-house function is able to evaluate the determinant of any symbolic square matrix reducing the computational cost and fastening the process when compared to the MATLAB built-in det(A) function.
The function uses the Leibniz formula for determinants recursively in order to calculate the determinant as the sum of the determinants of 2x2 matrices.
I have tested it with a full 10x10 symbolic matrix and it worked perfectly whereas using det(A) the computer ran out of memory and stopped the calculation.
