Don’t change the question after someone has answered the question!

oh sorry..

[Image Analyst]

Yes, because not madhan's answer of any(pic) doesn't work, though it might have worked on the prior question. Can you explain WHY you need this, because maybe you think you need it but you really don't need it to accomplish whatever it is you want to accomplish. Please supply the larger context of why you want this.

[Jassy]

Sorry. I don't see reply. I see did after i edited.

I need this because I need to count line in pic.

Ex 1 line

pic1 = [
      0 0 0 0 0 0 1 0 0 0
      0 0 0 0 0 1 0 0 0 0
      0 0 0 0 1 0 0 0 0 0
      0 0 0 1 0 0 0 0 0 0
      0 0 0 1 0 0 0 0 0 0
      0 0 0 1 0 0 0 0 0 0
      0 0 1 0 0 0 0 0 0 0
      0 0 1 0 0 0 0 0 0 0
      0 1 0 0 0 0 0 0 0 0
      1 0 0 0 0 0 0 0 0 0]
      
result1 = 1 1 1 1 1 1 1 0 0 0

Ex 2 line

      pic2 = [
      0 0 0 0 0 0 1 0 0 0
      0 0 0 0 0 1 0 0 0 0
      0 0 0 0 1 0 0 0 0 1
      0 0 0 1 0 0 0 0 1 0
      0 0 0 1 0 0 0 1 0 0
      0 0 0 1 0 0 1 0 0 0
      0 0 1 0 0 0 1 0 0 0
      0 0 1 0 0 1 0 0 0 0
      0 1 0 0 1 0 0 0 0 0
      1 0 0 1 0 0 0 0 0 0]
  
result = 1 1 1 2 2 2 2 1 1 1

The code below in my Answer also works for your pic2, giving you the results you stated. Are you looking below in the "Answers" section, or did you not scroll down and are just looking at the "Comments" section up here?

Answer 1

[Image Analyst]

This will give you

result =

1 1 1 2 2 0 0 0 0 0

exactly as you wanted (in your current version of the question):

pic = [
      0 0 0 0 1 0 0 0 0 0
      0 0 0 1 0 0 0 0 0 0
      0 0 0 0 1 0 0 0 0 0
      0 0 0 1 0 0 0 0 0 0
      0 0 0 1 0 0 0 0 0 0
      0 0 0 1 0 0 0 0 0 0
      0 0 1 0 0 0 0 0 0 0
      0 0 1 0 0 0 0 0 0 0
      0 1 0 0 0 0 0 0 0 0
      1 0 0 0 0 0 0 0 0 0]
[rows, columns] = size(pic);
for col = 1 : columns
	[~, result(col)] = bwlabel(pic(:, col))
end

[Image Analyst]

If you want to count the total number of lines in the image, instead of how many lines are in each column, you can just use connected component labeling, like

[labeledLines, totalNumberOfLines] = bwlabel(pic);
