Help making my code more efficient

1 view (last 30 days)
So I have the below code I use for post-2P image proccessing. I am fairly new to Matlab so I apologize if this is a rudamentatry question and I would appreciate guaidance more so than an answer I can copy and paste. Bsacilly most of the code I feel like could be made into a nested loop but I am not quite sure how to structure that. Thanks in advance!!

Below I created a nested loop as requested. If the comments do not provide enough guidance, please let me know.
x = 2590;
for i = 1:20
for ii=x*(i-1)+1:x*i % modified, replaced the numbers you had with equation
QQ=squeeze(Q(ii,:,:));
QQ=cell2mat(QQ);
QQ=reshape(QQ,512,796);
if ii == x*(i-1)+1 % modified, replace number you had in each iteration with i-1
imwrite(QQ,['E1_1018_' num2str(i) '.tif'],'tif'); % Replaced hardcoded numbers with a num2str function that converts i from a number to a string
else
imwrite(QQ,['E1_1018_' num2str(i) '.tif'],'tif','writemode','append');
end
end
end
