Can someone help me to understand this loop

c = 0;

    for j = 1:data:data*no_gb

        c = c + 1;
        tmp_tr = img_out_train(:,:,c);

        tmp_tr = im2double(tmp_tr);

        [cF] =DCT_block_palm_16x16(tmp_tr,overlap);

        GB_pony(j:data_n*c,:) = (cF(1:data_n,:));

    end

We can't tell you much based on the information provided. Apparently img_out_train is a set of intensity images (one for each value of c) and you are doing something to them using a mystery function DCT_block_palm_16x16.

Thanks Andrew. Yes img_out_train is a set of images. DCT_block_palm_16x16 is a call function.There is a mistake on the first statement.Below is the correct code.what i dont understand is the last statement of the loop.Your help will be much appreciated

data_n =20, no_gb=32

c = 0;

for j = 1:data_n:data_n*no_gb

c = c + 1;

tmp_tr = img_out_train(:,:,c);

tmp_tr = im2double(tmp_tr);

[cF] =DCT_block_palm_16x16(tmp_tr,overlap);

GB_pony(j:data_n*c,:) = (cF(1:data_n,:));

end
