Dynamically Naming Structures

I have a question that is proving very difficult to somebody with only two months of experience in Matlab. I want to create a series of nested structures, and need to have one level generate the variable dynamically. Here's my proposed structure:

pool.sub_X.trial_X.variables

pool: a structure containing all the data

sub_X: a structure for each of the subjects that were tested in an experiment. I would like X to be dynamically changed based on a numerical value it is given, resulting in a series of structures sub_1, sub_2, sub_3, etc. Total number of structures that will need to be created is unknown. (I was having trouble with this as it kept telling me I needed a cell array, and it wouldn't convert from a number to a cell.)

trial_X: similar to sub_X, based on the trial number it is given.

variables: this will several, predefined values that will be either numerical data or strings. I'm thinking the best way to do this would be to have a template structure that could easily be assigned to each trial.

I'm not sure if this all makes sense, but any pointers would be greatly appreciated. :)

Sure, see the dynamic field names part of this description:
