Looping through Different Variables

I am trying to loop through different matrices. For example I want to do something like this:

for i = [ Variable Constant Dataset Slopes ...]; ( where these are all arrays )

      averageNumber = average(i(2,:));

      matrix = [matrix averageNumber] (matrix is initialized before loop)

end

I know this does not work, but its the best way to portray my problem.

Any help would be appreciated!

edit: The variables are not necessarily the same size. They are 2-D arrays however. Basically I want to preform the same list of operations on different variables.

I don't fully understand your pseudocode. If the matrices you're trying to loop through are 2D arrays of the same size MXN, then they should all be made slices of an MxNxP three-dimensional array A. Then, you would do something like this,

for i=1:P

   currentMatrix=A(:,:,i);

   %do other stuff

end

[Matt J]

If the matrices are not the same size, they should be put into a cell array C{i}, i=1...P and looped over by doing

 for i=1:P
   currentMatrix=C{i};
   %do other stuff
 end

matlab doesnt allow for brace indexing

"matlab doesnt allow for brace indexing"

In fact it does. Both cell arrays (as Matt J recommended in this comment) and tables use curly braces to access data arrays within the container array. This is clearly explained in the documentation:
