Creating multiple matrices with linspace
显示 更早的评论
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

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
