Ok here is my issue:
I have a vector called collection with some elements:
collection = [1 2 3 4 5 6 7 8 9 0];
I also have a variable called x that stores the string 'collection'
x = 'collection';
I would like to know how can I plot the values of the vector 'collection' by using the variable x that has the name of the vector stored inside it. I would like to do something like this:
plot(x)
and that the points from the vector collection get plotted. Thank you very much!!

You will need to use plot(eval(x)). If inside a function, use plot(evalin('base',x)).
Better way is to plan and re-organize your data structure. For example, use structure:
Data.collection=1:10;
x='collection';
plot(Data.(x))
