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. See also PARFOR, IF, WHILE, SWITCH, BREAK, CONTINUE, END, COLON. Documentation for for doc for
