For larger matrices like 3x3, calculate the determinants of each sub-matrix. The determinant of the sub-matrix obtained by removing the first row and the first column is: ei−fh e i − f h $, do the same for all combinations of ...Basically, the cofactor is either M ij or M ij where the sign depends on the location of the element in the matrix. For that reason, it is easier to know the pattern of cofactors instead of actually remembering the formula. If you start in the position corresponding to a 11 with a positive sign, the sign of the cofactor has an alternating pattern.The inverse of a matrix may be computed by following the steps below: Step 1: Determine the minor of the provided matrix.
