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 WebLong story short, multiplying by a scalar on an entire matrix, multiplies each row by that scalar, so the more rows it has (or the bigger the size of the square matrix), the more times you are multiplying by that scalar. Example, if A is 3x3, and Det (A) = 5, B=2A, then Det (B) = 2^3*5=40. Det (kA)=k^n*Det (A).
