Hi, i have pk=1x6 cell,each cell contains 192x192 data, i need to divide each 192x192 data into 3x3,then perfrom "AND",i.e result=64x64x6

plz check whether my code is correct

fun=@(block_struct) sum(block_struct.data);
for ol=1:length(pk)
result(:,:,ol)=blockproc(pk{ol},[3 3],fun)
end

fun=@(block_struct) sum(block_struct.data(:));

i got error "Subscripted assignment dimension mismatch."

Works for me.

fun=@(block_struct) sum(block_struct.data(:));

pk = {randi(64,192,192),randi(64,192,192), randi(64,192,192),randi(64,192,192)};
for ol=1:length(pk); result(:,:,ol)=blockproc(pk{ol},[3 3],fun); end

Do you possibly have a result variable left over that is the wrong size?

Sir, i have already stored a variable named 'result',code is working thanks a lot

Sorry for asking relevant question.

My p2=1x1x6 cell, each (i.e,1x1x1 contains 6 21x21 data, likewise 1x1x2 contains 6 21x21 data and so on). now i need to perform the same blockproc for all these 21x21 data, totally 36 21x21 datas, how to do, give some idea sir
