EDIT: As JS mentioned, structs are generally better for dynamic field names. You can use them like this:

varnames = {'foo', 'bar'};
str = struct;
for i = 1:length(varnames)
   str = setfield(str, varnames{i}, rand); %#ok
end

str =    
     foo: 0.4854
     bar: 0.8003

Or even more simply, like this:

str2.('alpha') = 123;
str2.('beta') = 1:10;
