I used findgroup and get a G as the output. I would like to apply G to a numeric matrix (MxN) to split the matrix into several cells such that, each cell contains a smaller sized matrix (mxN).
How to write the code? I tried this but got error: Not enough input arguments. out = splitapply(mat2cell, mat, [1, 1], G); Thanks.

You use "mat2cell", which is a function call. Do you mean "@mat2cell", which is the function handle?

splitapply(@(m) {m}, mat, G)
what you're after?
You could do the same with mat2cell if you really wanted, it's just slightly more complicated and pointless:
splitapply(@(m) mat2cell(m, size(m,1), size(m, 2)), mat, G)

I am assuming you are using the "findgroups" and "splitapply" functions to group a matrix into cells. From the error, it looks like the function "mat2cell" being applied to each group is not getting the required matrix argument.
Maybe the second format specified here to use splitapply might help:
