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 … WebThe first thing to note is that the determinant of a matrix is defined only if the matrix is square. Thus, if Ais a 2×2 matrix, it has a determinant, but if Ais ... This last example illustrates perhaps the easiest wayto evaluate the determinant of a matrix. That is, use the elementary row or column operations to get a row
