I have a problem in finding eigenvalues of a 12*12 because the 12*12 matrix is so complicated

so i decided to first make my 12*12 matrix in form of upper triangular form but I don't know how can I do it with MATLAB or mathematica?

can you please tell me that what is the formula in MATLAB or mathematica for make an upper triangular matrix from my own 12*12 matrix?

thanks alot
