How to Access and Rename Doubles that are Stored in a Large Cell

I have a Cell that is 1x193. Each of the 193 elements is a 500x100 double.
I need to be able to access every element in this cell and rename each double to be Data1, Data2, Data3, etc. such that I can perform means on the rows of Data1, Data2, etc.
Does anyone have suggestions for how to accomplish this?

Use indexing.
Creating/accessing numbered variables would be entirely the wrong way to go about this:
Indexing is simple, neat, and very efficient. Using numbered variables is a sign that you are doing something wrong.

You no need to rename every elecment(500x100 double) of the cell which leads much complications, you can perform your operation directly using command cellfun
result_mean = cellfun(@(x)mean(x, 2), cell_array, 'UniformOutput', false); % cell_array is your vartiable
You can access mean values of the data as
result_mean{1}, result_mean{2}..result_mean{193}; % for mean values of the each row of the double array

Do NOT use datastore as a variable name, it is the name of an important inbuilt function.
Where C is your cell array, calculate the mean of each row:
A = cat(3, C{:});
M = mean(A,2)
It will have size 500x1x193. Use indexing to access particular pages, or permute or reshape to rearrange those dimensions. Avoid squeeze.
