I have the variables day1,day2,day3....day15. I want to get the data of each variable within a loop. How I can do it?
Thank you in advance

Hello,
A simple solution would be:
Days = [day1 day2 day3 ... day15];
Then call Days(:,i) for the ith days data if it's a vector (assuming column vectors), or just Days(i) if it's a scalar.
Hope this helps!

The "data of each variable" and the variable itself are one and the same thing. Just assign it to another variable if you want, or just start using it.
someOtherVariable = day1;
someOtherVariable2 = day2 * pi * log(42);
someOtherVariable3 = day5 * cos(day12) + day9;
result = SomeFunction(day7);
and so on. You don't need to do anything special to the variable to access it's "data". The variable and its data are the very same thing.

See the FAQ for why this is a horrible idea: http://matlab.wikia.com/wiki/FAQ#How_can_I_create_variables_A1.2C_A2.2C....2CA10_in_a_loop.3F
