A cofactor corresponds to the minor for a certain entry of the matrix's determinant. To find the cofactor of a certain entry in that determinant, follow these steps: Take the values of i and j from the subscript of the minor, Mi,j, and add them. Take the value of i + j and put it, as a power, on −1; in other words, evaluate (−1)i+j. Free matrix Minors & Cofactors calculator - find the Minors & Cofactors of a matrix step-by-stepMultiply this determinant by (-1)^ (1+1) = 1 to get -3. Place this value in the first row and first column of the cofactor matrix. Repeat these steps for each element in the matrix to obtain the full cofactor matrix. The resulting cofactor matrix will have the same dimensions as the original matrix.
