MATLAB: Apply function to two cell arrays element-wise

Question

I have two cell arrays, xdata and CDF. I want to apply kstest element-wise to each pair of xdata and CDF cells (e.g., xdata{1} and CDF{1}, xdata{2} and CDF{2}, etc.).

Each cell of xdata is nx1 (data sample values), and each cell of CDF ix nx2 (theoretical [x,CDF] values).

I can do this with a for loop:

for i=1:length(xdata)
  [h{i},p{i},ks2stat{i}]=kstest(xdata{i},CDF{i});
end

But I'm wondering if there's a clever way to do it more cleanly with anonymous functions and cellfun? Something along the lines of:

[h,p,ks2stat]=deal(cellfun(@(xc) kstest(xc(:,1),xc(:,2:3)),{[xdata CDF]},'Uniform',0));

Any ideas would be appreciated. Thanks!

You're overcomplicating:

[h, p, k2stat] = cellfun(@kstest, xdata, CDF, 'UniformOutput', false);
