Determinant of a matrix using recursion

WebI have been recently trying to attempt to write an algorithm in C# that would calculate the determinant of a matrix via recursion using the expansion of minors method. I understand that there are other methods such as upper and lower triangular forms which give the same solution, but for the moment I am trying to figure out this problem and I ... WebMay 7, 2024 · Unfortunately this is a mathematical coincidence. It is NOT the case that the determinant of a square matrix is just a sum and difference of all the products of the diagonals. For a 4x4 matrix, you expand across the first column by co-factors, then take the determinant of the resulting 3x3 matrices as above.
