I = your_image;
[rows,cols] = size(I); % dimensions of your image
M = cell(8,8);
for k=1:8
for l = 1:8
M{k,l} = I( (rows*(k-1)/8 + 1):(rows*k/8) , (cols*(l-1)/8 +1):(cols*l/8) );
M{k,l} = reshape8M{k,l},(rows*cols/64),1); % reshape into single column
end
end

here with the typo in the 7th line corrected:
I = your_image;
[rows,cols] = size(I); % dimensions of your image
for k=1:8
for l = 1:8
M{k,l} = I( (rows*(k-1)/8 + 1):(rows*k/8) , (cols*(l-1)/8 +1):(cols*l/8) );
M{k,l} = reshape(M{k,l},(rows*cols/64),1); % reshape into single column
end
end
