A determinant is defined for square matrices only.

To find the determinant of the matrix you need to:

  • find all n-tuples of elements of the matrix such that each row and each column of the matrix is represented.
  • calculate the product of the elements.
  • calculate the sign for that term. To see how this is done, see below.
  • calculate the sum of the signed products: that is the determinant.

To calculate the sign for the product of the n-tuple, arrange the elements in row order. Swap the elements, two at a time, to get them in column order. If the number of swaps required is even then the product is assigned a positive sign, and if odd then a negative sign.

What is the determinant of a 2x3 matrix?

The determinant function is only defined for an nxn (i.e. square) matrix. So by definition of the determinant it would not exist for a 2x3 matrix.

No. A square matrix has an inverse if and only if its determinant is nonzero.


What is the minor of determinant?

The minor is the determinant of the matrix constructed by removing the row and column of a particular element. Thus, the minor of a34 is the determinant of the matrix which has all the same rows and columns, except for the 3rd row and 4th column.
