A cofactor matrix is a matrix of cofactors, where each cofactor is obtained by removing a row and column from the original matrix and calculating the determinant of the resulting matrix. This process involves a series of calculations, including the multiplication and addition of elements from the original matrix. The resulting cofactor matrix can be used to calculate the determinant and inverse of the original matrix.
A cofactor is a signed minor, which means it is a minor multiplied by (-1)^(row + column). A minor, on the other hand, is the determinant of a matrix obtained by removing a row and column from the original matrix.
