Hi everyone, I am using intersect function to compare different arrays and find find out the common rows between them. But I am facing a problem with its result. When I am comparing an array 'H' which is of size 155010x3 double with itself i.e. 'H' it is giving the result as 25896x3 double. However both of them are same so the result should be actual size of 'H' i.e 155010x3 double.
Picture is also attached below.
Anyone please guide me about this.

@yu sh: the screenshots look lovely, but it is much easier for us when you give actual text that we can run. Also please upload the data using the paperclip button.

According to the documentation, intersect reports only the unique rows, without repetition.
You may be able to glean more info from the other output arguments ...
[HH,ia,ib] = intersect(H,H,'rows')
which will indicate which rows of the input matrices were included in the intersection.
