WebThis is a 3 by 3 matrix. And now let's evaluate its determinant. So what we have to remember is a checkerboard pattern when we think of 3 by 3 matrices: positive, negative, positive. So first we're going to take positive 1 times 4. So we could just write plus 4 times 4, the determinant of 4 submatrix. WebNov 3, 2024 · The cofactor matrix of a given square matrix consists of first minors multiplied by sign factors:. The first minor is the determinant of the matrix cut down from the original matrix by deleting one row and one column. To learn about determinants, visit our determinant calculator.; The sign factor is -1 if the index of the row that we removed …
