WebElementary Row Operations to Find Inverse of a Matrix. To find the inverse of a square matrix A, we usually apply the formula, A -1 = (adj A) / (det A). But this process is lengthy as it involves many steps like calculating cofactor matrix, adjoint matrix, determinant, etc. To make this process easy, we can apply the elementary row operations.
