I am trying to convert a matlab code to Opencv Code.
I need to convert the below code to opencv.
I would like to know is there any equivalent of matlab find function in opencv.

S has (x,y) data and size of S is 100x2

ind = find(S(:,1) >= xm & S(:,1) <= xM & S(:,2) >= ym & Sm(:,2) <= yM);
Snew = S(ind,:);

Edit: In the question OpenCV function similar to matlab's “find”, the output Snew and the input S are of same size, but here in my question, Snew is not of the same size as S.. For example:

S = [ 76    96
    26    55
    51    14
    70    15
    90    26]

ind = find(S(:,1) > 50);
Snew = S(ind3,:);

Snew = [ 76    96
    51    14
    70    15
    90    26]

As you can see, Snew and S are not of same size...

The im in the refered question is of the same size of initial input im...

@EdChum I have edidted my question and reason why its not duplicate. – 2vision2 Feb 14 '13 at 04:45
indeed this question does not seem a duplicate to me, the title of the duplicate is misleading and its accepted answer does not answer this question. – Gianni Jul 01 '19 at 12:00
