How to overwrite some workspace variables in a dynamic program?

Hello,
I have a dynamic program that creates objects in the workspace (datasets, matrices) with the same name each loop but the objects themselves change size each time. Each loop I save them to a data structure and don't want to clear out the workspace. What is the best practice for "overwriting"? Ideas I have are: 1) create a new initialized matrix each time with zeros to wipe out the old matrix or 2) remove the matrix with MLDeleteMatrix(var_name) but this doesn't seem to work with my version (R2011b).

Both ideas are good. If 2. doesn't work, try
clear('var_name')
or
clear var_name

You can just reassign the variable with new content, MATLAB try to merge the new content with the old, nor will it leak memory.
>> A=ones(100);
>> size(A)
ans =
100 100
>> A=ones(25);
>> size(A)
ans =
25 25
