Hello,
According to the Matlab documentation ( http://www.mathworks.com/help/distcomp/run-built-in-functions-on-a-gpu.html ), I can create a sparse gpuArray by "either by calling sparse with a gpuArray input, or by calling gpuArray with a sparse input." Neither of these seems to work:
x = sparse([0 2 0; 0 5 0; 0 1 0])x = (1,2) 2 (2,2) 5 (3,2) 1 m = gpuArray(x) Error using gpuArray Only full arrays of fundamental numeric types or logical types are supported for GPU arrays.
Or alternatively:
x = gpuArray([0 2 0; 0 5 0; 0 1 0]) x = 0 2 0 0 5 0 0 1 0 X = sparse(x) Undefined function 'sparse' for input arguments of type 'gpuArray'.
Am I doing something wrong?
Thanks!
