A(N,N): matrix

First, i want to give the matrix from my keyboard. Then calculate the determinant of A

Thanks!

You can define the matrix like so (semicolons can be used for line breaks)

A = [1 2 3; 4 5 6; 7 8 0]
A =
     1     2     3
     4     5     6
     7     8     0

Then you calculate the determinate by using DET

det(A)

ans =
           27

A = [ 1 2 3 4;
      5 6 7 8;
      1 2 3 4;
      5 6 7 8];
det(A)
