Kind time of the day, dear inhabitants of the forum. I want to ask whether anyone can help me calculate the clustering of kmeans on a GPU it is not included in the standard function gpuArray but it can be calculated as a user-defined function But how to do that? I'm new to matlab and can not figure out how to implement it.

      gpuArray support for kmeans was added to MATLAB in R2016a
>> help gpuArray/kmeans
 kmeans K-means clustering for GPU data
    IDX = kmeans(X, K)
    [IDX, C] = kmeans(X, K)
    [IDX, C, SUMD] = kmeans(X, K)
    [IDX, C, SUMD, D] = kmeans(X, K)
    [ ... ] = kmeans(..., 'PARAM1',val1, 'PARAM2',val2, ...)
      Example:
          N = 1e6;
          X = gpuArray([randn(N,2)+ones(N,2); randn(N,2)-ones(N,2)]);
          [cidx, ctrs] = kmeans(X, 2);
      See also kmeans, gpuArray.
