Question

For this question, I’m supposed to create a NxN powers table in matlab using arrays.

The code I have so far is as follows:

C = [];
D = [];

N = input('Enter the value you would like to use for your NxN Powers Table: ');

for i = 1:N 
    for j = 1:N  
        C = [C;i^j];    
    end  
    C = transpose(C);
    D = [D;C];  
    C = [];
end

D

This code works perfectly fine for any numbers from 1-9, as soon as I enter anything greater than that, it prints out weird values.

Here is the output I have using 5 as an input, and the second one is using 10 as an input.

Enter the value you would like to use for your NxN Powers Table: 5

D =

       1           1           1           1           1
       2           4           8          16          32
       3           9          27          81         243
       4          16          64         256        1024
       5          25         125         625        3125


Enter the value you would like to use for your NxN Powers Table: 10

D =

  1.0e+010 *

Any ideas what could be wrong with my code? Seems like a simple fix, I just can’t figure out whats wrong with it. Any help is greatly appreciated. Thanks

Notice the 1.0e+010 *. It means that the numbers should be multiplied by 10000000000. Five digits are not enough to print it. Insert format long or format short g to see the whole numbers.
