Creating multiple matrices with linspace

Hello all,

I'm trying to create multiple matrices as follows possibly using linspace:

x = [111;111;111]

x = [222;222;222]

x = [333;333;333]

and so on.

I would then use these matrices as a constant in matrix multiplication in an equation.

The reason would be so I don't have to create 100 matrices manually.

Would this be possible without a loop?

Thanks in advance!

"Would this be possible without a loop?"

One simple and efficient MATLAB approach:

M =  [111;111;111].*(1:9)

And then you can trivially access the columns using basic indexing. Hopefully you are not intending to create 100 separate variables in the workspace, which would be about the worst approach for this task: https://www.mathworks.com/matlabcentral/answers/304528-tutorial-why-variables-should-not-be-named-dynamically-eval

Thank you for the reference material I will definitely look into this since I was already creating quite a few variables making the code slow. Much appreciated!

Why do you need linspace for this? You can just create such matrices like this

a = [111; 111; 111];
for i = 1:9
    x = a*i;
    disp(x)
end

Ok awesome! This did the trick. Thank you!
