This will yield the inverse of the original matrix, provided the determinant of the original matrix is not zero. Next, we write down the matrix of cofactors by putting the i, j -cofactor into the i -th row and j -th column:. In consequence,. Fortunately, our cofactor expansion calculator can do all the hard work for you! The determinant of such a matrix is equal to d as well. For instance, if you have a 3x3 matrix, to calculate the cofactor of the element in the second row and third column, i. A minor is determined by eliminating the row and column associated with a particular element and then calculating the determinant of the resulting submatrix. Yes, the calculator uses precise mathematical formulas and algorithms to ensure accurate calculations. A cofactor is calculated from the minor of the submatrix. Make sure that the number of rows and the number of columns are the same, as a matrix of minors can be calculated only for square matrices. To find the cofactor matrix of A , follow these steps: Cross out the i -th row and the j -th column of A. Accept Read More.
