Inverse of a matrix exists only if the matrix is non-singular i.e., determinant should not be 0. If you put matrix[j][i]/matrix[i][i] instead of ratio inside third nested for loop, it throws division by zero run time error. You have not taken care of such situation. If the determinant of matrix is non zero, we can find Inverse of matrix. http://c.happycodings.com You can find c codes at this place. i just got the thought that to find the determinant it would be recursive . Ratio actually prevents the division by zero error. printf("\n Determinant of Matrix A is %d . This program takes a matrix of order r*c from the user and computes the transpose of the matrix.
