How can i put my output numbers in for loop to an array
显示 更早的评论
z=('/Users/fatihnurcin/Desktop/Dandnd/dilated')
cd(z)
list = dir('*.bmp');
for i = 1:length(list)
img{i} = imread(list(i).name);
end
for i = 1:length(list)
a=img{i};
b=im2bw(a,0.20);
figure
subplot(1,3,1);
imshow(b)
c=b(120,100:250);
subplot(1,3,3);
plot(c);
for n=1:length(c);
d= padarray(c,[0 1],'replicate','post');
e(n)=d(n)-d(n+1);
left=find(e==1);
right=find(e==-1);
f=right-left;
end
f
end
This is my whole code, it takes a row from a binary photo and tries to find where its black and where its not and calculate the black area so i want to ask how can i put my outputs(outputs are numbers calculated due to black arena) in an array, i couldn't do it by adding (n) to left and right,
left(n)=find(e(n)==1);
right(n)=find(e(n)==-1);
f(n)=right(n)-left(n);
I need an urgent help , i need to deliver my project in 2 days :/

reformatted to be readable.
z=('/Users/fatihnurcin/Desktop/Dandnd/dilated')
cd(z)
list = dir('*.bmp');
for i = 1:length(list)
img{i} = imread(list(i).name);
end
for i = 1:length(list)
a=img{i};
b=im2bw(a,0.20);
figure subplot(1,3,1);
imshow(b)
c=b(120,100:250);
subplot(1,3,3);
plot(c);
for n=1:length(c);
d= padarray(c,[0 1],'replicate','post');
e(n)=d(n)-d(n+1);
left=find(e==1);
right=find(e==-1);
f=right-left;
end
f
end

This assumes the bitmaps are all the same size:
myArray = [img{:}];

If this answers your question, please mark this as the correct answer. It helps my reputation points on MATLAB answers.

Can you give me some data so I can work out the issue?

Honestly, it is clear to me you don't really know what you are doing with MATLAB. After this project is done, you need to read up "getting started" documents for MATLAB. The code below is ugly but works. I believe it is what you want as well.
list = dir('*.bmp');
% preallocate cell array
img = cell(length(list),1);
f = cell(length(list), 250-100);
for i = 1:length(list)
img{i} = imread(list(i).name);
end
for i = 1:length(list)
a=img{i};
b=im2bw(a,0.20);
figure;
subplot(1,3,1);
imshow(b)
c=b(120,100:250);
subplot(1,3,3);
plot(c);
for n=1:length(c);
d= padarray(c,[0 1],'replicate','post');
e(n)=d(n)-d(n+1);
left=find(e==1);
right=find(e==-1);
f{i, n} = right-left;
end
end

I guess you may go for index mapping. I just give you Idea try this once
for m=1:4
for n=1:4
X(m,n)=x(4*(m-1)+n);
end
end
x is the input which of your interest to put into an array X

what would you do if during the loop, those arrays are different lengths?
