# Sir whats the functioning of this code:

Asked by Vandana on 19 Sep 2013
```count=0;
j=1;
for i=1:ro
if(rV(i)>0)
rda(j)=i;
rca(j)=1;
count=0;
j=j+1;
elseif(count==0)
rda(j)=i;
rca(j)=0;
j=j+1;
count=1;
else
count=1;
end;
end;
```
```flag=1;
k=1;
for i=1:j-2
if((rda(i+1)-rda(i))>=12)
if(flag==1)
ra(k)=rda(i);
k=k+1;
flag=0;
end;
else
flag=1;
ra(k)=rda(i);
end
end
```

where ro means number of rows and rv means row variance and rda and rca are normal variable.

[EDITED, Jan, code indented for demonstration]

Tip: Before pasting your code in here, when it's still in MATLAB, type ctrl-a (to select all the code), and then Ctrl-i (to fix the indenting).

Vandana on 19 Sep 2013

this is the formatted code sir I don't know sir why preview is looking like this.sir I want explaination of each line what it is doing.sir before this code I calculated the rowwise variance and column wise variance.

thank you

@Vandana: Did you try Ctrl-A Ctrl_I for an auto-indentation in Matlab's editor?

It looks like the code functions to produce arrays called ra, rca, and rda. It looks like perhaps some kind of counting or thresholding operation but with no comments it's hard to figure out their intent. Why don't you ask the author, and ask them why they write code with no comments in it? Or ask them what their intent is?

Image Analyst on 20 Sep 2013

I don't know what that means.

It appears to be Hindi, and it appears that Google Translate does a terrible job with romanized Hindi. My investigation is suggestive that "kuch" translates as "something" or perhaps "anything". I don't know... "please edit the code" ??

"sir mai kuch edit karti hu" is in Hindi, that means "sir I will edit something"

Dear Vandana, I think your code is associated with some previous values. It looks like it is only a small part of some code. Try to identify variable: ro, rV, rda, & rca.
