Hello, I have a vector named TB consisting of the mean of variables named T1B, T2B, ..., T44B. I imported these variables from an excel file. Is there a way to simplify the code?
TB=[mean(T1B), mean(T2B), mean(T3B), mean(T4B), mean(T5B),...
mean(T6B), mean(T7B), mean(T8B), mean(T9B), mean(T10B), mean(T11B),...
mean(T12B), mean(T13B), mean(T14B), mean(T15B), mean(T16B), mean(T17B),...
mean(T18B), mean(T19B), mean(T20B), mean(T21B), mean(T22B), mean(T23B),...
mean(T24B), mean(T25B), mean(T26B), mean(T27B), mean(T28B), mean(T29B),...
mean(T30B), mean(T31B), mean(T32B), mean(T33B), mean(T34B), mean(T35B),...
mean(T36B), mean(T37B), mean(T38B), mean(T39B),mean(T40B), mean(T41B),...
mean(T42B), mean(T43B), mean(T44B)];

Try something like:
for i=1:num_elems %assuming you know the number of elements and have set it before hand
eval(['TB(i) = mean(T' num2str(i) 'B);'])
end
What this does is that it evaluates the string as matlab code. Using eval is not recommended in general, but might make life easier for you here. (See Using Eval)
