Beginner: How do I loop through strings ?

I have the following code:

br1=cell2mat(br1);

br2=cell2mat(br2);

...

br49=cell2mat(br49);

br50=cell2mat(br50);

How can I loop from br1 to br50? I tried using for n=1:50 eval('br' + n '=cell2mat(br' + n + ');'); but it doesn't work ("error using "+", incompatible array size").

This is the question asked most frequently by beginners. The answer of the experts is always the same: Don't do this.

This is exhaustively explained here: TUTORIAL: Why and how to avoid Eval

Do not hide an index in the name of a variable, but use an array and an index:

brC = cell(1, 50);
for k = 1:50
   brC{k} = cell2mat(br(k));
end

This is some pseudo-code only, because it is not clear, what the contents of your variables is.
