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 Mi,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.

Inputs

 
  • 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

Output

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