Determinant of a 5x5 matrix
I'm in desperate need of knowing how to do this.
I already know how to get determinants of 3x3 and 4x4 matrices, but I just don't have a clue when it comes to 5x5, and google doesn't help, as I haven't found any real 5x5 examples yet (lots of 4x4 and 3x3, but only small tips for 5x5).
I understand this may be because of the large quantity of operations needed, but my assignment is to do this both MANUALLY and by making a program in C++, the problem is I can't program if I don't have a clue how to do it manually. So if anyone has a full step-by-step 5x5 example I would greatly appreciate it. Any example will do as long as it doesn't have more than one 0.
P.D. I apologize if my grammar is bad, my native language is spanish.
