arrayfun is for applying a scalar operation element-wise across an array. You should not be using it to wrap knnsearch. Just call knnsearch with your gpuArray inputs.
See help gpuArray\knnsearch.

I'm sure! Probably you don't have R2016b.

But it seems the GPU version of knnsearch only support brute force method, for large data set, it is slower than the CPU version with kdtree algorithm.
