Address a variable using the name of another variable

Greetings. I`m using Matlab to analyse some of my biology experiments and I`m currently having problems. Since I`m using a lot of strange variables and a lot of data, I`ll summarise my problems in this example:
% create a 1x2 cell with chars
list{1,1}='A';
list{1,2}='B';
%create a simple vector
testA=[1 2 3 4 5 6 7 8 9 10];
%get the mean
mean_testA=mean(testA);
What I want is to be able to use the char in “list” to address testA.
Something like mean_testA=mean(test list{1,1})
Thank you!

Sounds like you probably want to look into using structures with dynamic fieldnames

It seems to make the most sense to put your actual data in test_list{i}, e.g.,
test_list{1,1}=testA;
Then your command mean_testA=mean(test list{1,1}) will do exactly what you want. You can also do things like
S.A=testA;
S.B=whatever;
testlist=fieldnames(S);
mean_testA = mean(S.(testlist{1}))
mean_testB = mean(S.(testlist{2}))
