Simple For Loop Question about Creating Variables

Hi,

I would like to work with quite a big amount of variables and would like to know if there is a shortcut to reduce the amount of lines in my code.

I tried using a for loop and replaced the 1,2,3,4,5 etc with i and then run it for the corresponding amount of iterations (in this case i= 1:5), but it didn't work out.

Here is some small example of the issue:

A1 = [100;150];
A2 = [200;250];
A3 = [300;350];
A4 = [400;450];
A5 = [500;550];

A1x = mean(A1);
A2x = mean(A2);
A3x = mean(A3);
A4x = mean(A4);
A5x = mean(A5);

Particularly in the second part of the code, I would like to change 1 to 5 to a more simplified way.

Thanks

Create a matrix from the ‘A’ vectors, then take the mean of the columns:

A1 = [100;150];
A2 = [200;250];
A3 = [300;350];
A4 = [400;450];
A5 = [500;550];

N = 5;
for k1 = 1:N
    A(:,k1) = eval(sprintf('A%d',k1));
end

Ax = mean(A)

EDIT — Added loop.
