We have studied about matrices before, like,


Determinant is a special number calculated from square matrix

So, determinant of matrix A & B is possible



Determinant’s of matrix C is not possible

Because matrix C is not a square matrix


For matrix A,

We denote determinant as

det A


det (A)





A = [3 2 1 4] B = [9 2 1 5 -1 6 4 0 -2] C = [3 2 1 4]
