Determinant of symbolic matrix
Matrix computations involving many symbolic scalar variables can be slow. To increase the computational speed, reduce the number of symbolic scalar variables by substituting the given values for some variables.
The minor expansion method is generally useful to evaluate the determinant of a matrix that contains many symbolic scalar variables. This method is often suited to matrices that contain polynomial entries with multivariate coefficients.
