Calling Variables from the Workspace

Hello. I have some variables in the workspace and they are named Cap# (the # stands for a number, so it could be 1,2,3,etc.). I want to create a loop so I can plot each variable from that workspace. They all differ by the number (Cap1, Cap2, Cap3, etc.). At the moment, I have to plot each variable manually and because there are many of them it is not efficient. Is there a way to just plot each one using a loop?

Go back to your variable creation, and change all your variable creation to Cap{#}.

Example: 
  Cap1 = [ 1 2 3 4 5]   ==>     Cap{1} = [ 1 2 3 4 5];
  Cap2 = [ 1 2 3 4 5]   ==>     Cap{2} = [ 1 2 3 4 5];
  Cap3 = [ 1 2 3 4 5]   ==>     Cap{3} = [ 1 2 3 4 5];
  ...

Then you can do your loop like:

   for j = 1:length(Cap)
      plot(Cap{j});
   end

You're facing difficulty now because you've named your variables incorrectly like Cap1, Cap2, etc. Read this:
