有限数学 示例

Choose the row or column with the most elements. If there are no elements choose any row or column. Multiply every element in column by its cofactor and add.

Consider the corresponding sign chart.

The cofactor is the minor with the sign changed if the indices match a position on the sign chart.

The minor for is the determinant with row and column deleted.
