How to change from cell to array

Hi all,

I want this code to run on the GPU.

Maybe O = (num2cell (O, [1 2])) of the RainDetect function; The part is expected to be a problem.

Since this part is a cell, the gpu operation does not seem to work.

I want to change from cell to array, is there a good way?

O = gather(video_ycbcr(gpuArray(video))); % Transfer RGB to YCbCr and retain Y only
O_cpu = {};
O_cpu{1} = O(:,:,001:149);% Can be easily extend to multiple GPU
O_gpu{1} = gpuArray(O_cpu{1});% Move array from CPU to GPU for acceleration
R_gpu{1} = RainDetect(O_gpu{1},paras);
R_cpu{1} = gather(cat(3,R_gpu{1}{:}));

R = R_cpu{1};

%==============================================================================
function [R,iter]=RainDetect(O,paras)
[m,n,t] = size(O);

O = (num2cell(O,[1 2]));

R{1} = gpuArray(zeros(m,n));

B{1} = O{1}-R{1};

iter{1} = 0;

[R{2},B{2},iter{2}]=RainDetect_i(O{2},B{1},paras);

for i = 3:t
    disp(i);
    [R{i},B{i},iter{i}]=RainDetect_i(O{i},B{i-1},paras);
end

Read about cell2mat.

i get this Error: Error using cell2mat (line 7) Cannot support cell arrays containing cell arrays or objects.
