How to plot a vector using a variable that contains the name of the vector.

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))
