You need to create a matrix using the formula

You need to write a function to create a matrix using the formula

Create (i - row index, j-column index) N-th order matrix D according to the formula

D (i, j) = N * x * i + j * x^N, N=3

 FOR    Repeat statements a specific number of times.
    The general form of a FOR statement is:
  
       FOR variable = expr, statement, ..., statement END
  
    The columns of the expression are stored one at a time in
    the variable and then the following statements, up to the
    END, are executed. The expression is often of the form X:Y,
    in which case its columns are simply scalars. Some examples
    (assume N has already been assigned a value).
  
         for R = 1:N
             for C = 1:N
                 A(R,C) = 1/(R+C-1);
             end
         end
  
    Step S with increments of -0.1
         for S = 1.0: -0.1: 0.0, do_some_task(S), end
 
    Set E to the unit N-vectors
         for E = eye(N), do_some_task(E), end
 
    Long loops are more memory efficient when the colon expression appears
    in the FOR statement since the index vector is never created.
 
    The BREAK statement can be used to terminate the loop prematurely.
