MATLAB: Iterate through alphabetical names

alphabeticalloopnames

Hello there,
maybe it's a dumb question, but how do I iterate through alphabetical names? Assuming I have matrices A to D, then how can I use those names in a loop?
My approach would be to create a string
 names='ABCD'
and loop through those in a loop
 for i=0:4
  names(i)
 end for
But how can I use this for example for the following operation?
 boxplot(A(:))
If I simply use
 names='ABCD';
 for i=0:4
  boxplot(name(i)(:))
 end for
Then it doesn't work, of course. strcat does not do the job either.
I hope someone has an idea 🙂
Cheers

Not dumb at all.
You need to use the eval function in your loop:
A = rand(2,10);
B = rand(3,10);
C = rand(4,10);
D = rand(5,10);
names = 'ABCD';
for k1 = 1:length(names)
    figure(k1)
    boxplot(eval(names(k1)))
end
