`"[A]"_"i,j" = "sub-matrix"[ "i" , "j" ], "where " "i" , "j" " are the row & column excluded from matrix A"`

Enter a value for all fields

This vCalc equation computes the (i,j) minor or first minor of the square matrix **A** that is input. The minor of A is sometimes referenced as `M_"i,j"` or `"[A]"_(i,j)`. The (i,j) minor is the determinant of the sub-matrix formed by deleting the i-th row and j-th column of matrix **A**.

**Matrix A**: enter the elements in the 3x3 matrix**Index i**: enter the row index of the minor `"[A]"_"i,j"`**Index j**: enter the column index of the minor `"[A]"_"i,j"`

This equation outputs a single real value which is the determinant of the sub-matrix formed by excluding row i and column j.
