How to create a matrix (3*3) from 1 to 9 by using For loop like:

1 2 3

4 5 6

7 8 9

.................

for i=1:3 %row%

for j=1:3 %column%

a(i,j)= input('a=');

end

disp (a)

..................

I wrote this code, but I don't want to input the digits from 1 to 9 by keyboard. I want the computer enter these digits automatically by using For loop

I think you don't need any for loop to achieve this goal. try this code below:

reshape( 1:9, 3, 3) .'
