WebHow do I find the determinant of a large matrix? For large matrices, the determinant can be calculated using a method called expansion by minors. This involves expanding the determinant along one of the rows or columns and using the determinants of smaller matrices to find the determinant of the original matrix. matrix-determinant-calculator. en WebIf the determinant of an nxn matrix is not zero, then the columns span the entire space R". The row operation R2-R1-R2 (replacing row 2 by row 1 minus row 2) does not change the determinant. If one row of a matrix is a linear combination of two other rows, then the determinant is 0. For all nxn matrices A and B, we have det(A+B)=det(A)+det(B ...
