image - Matlab fast gpuArray visualization -


the task simple, processing gpuarray of descent size, 2048x2048, inside loop , want visualize generating image plot (or heat map) in real time.

a=gpuarray(...); i=nframes     a= ... ;     imagesc(a);     drawnow; end

now problem low framerate (<10 fps) when using imagesc() or imshow() though processing not take long. if want set 'cdata' image handle declared since beginning, forced move array cpu memory time expensive , defeats purpose.

is there specific tool useful accelerate visualization of gpuarrays?

i've watched webinar on solving pdes gpu presenter has code in real time. can watch video exact idea of i'm looking for.
