Determinant of matrix nxn
WebNo. We can just calculate the determinant of a 4 x 4 matrix using the "conventional" method, i.e. taking the first element of the first row, multiplying it by the determinant of its "augmented" 3 x 3 matrix and so on and so forth. The only problem is that for every dimension we go up, the whole process takes longer and longer. WebThe determinant of an n x n square matrix A, denoted A or det (A) is a value that can be calculated from a square matrix. The determinant of a matrix has various applications …
