I have an cell array (h) of 4X1. Inside the cell I have 4 matrices each of size 234X64X8. How to find mean of each matrix using mean(h,3)

The mean of a 3-D matrix along dimension 3 would be a 234X64 matrix. So for each of the cells in the 4 element cell array, you say you have 4 of those matrixes, for a total of 16 2-D matrices.
How do you have 4 matrices inside each cell? You can have only one matrix, unless each cell contains a 4 element cell array. So let's say you did, then for each of the cell array's 4 cells you would have 4 matrices (since each of the cells in the cell array somehow contains 4 3-D matrices). This would give a grand total of 16 234x64 matrices. Is that right? What do you want as the output to be?
If you want any more help, say what you want as the output, and attach your cell array in a .mat file with the paperclip icon. But after you read this:

Here is one way:
cellfun(@(x)mean(x,3),h,'UniformOutput',false)

To clarify, after @Image Analyst's comment ...
My solution assumes that you have one 3-dimensional array in each of your 4 cell elements. (That was how I interpreted your remark that you have 4 matrices.)
