MATLAB: Issues with intersect function

intersect funtion

Hello,
I am using intersect function with this following command :
[c, ia ib] = intersect(Signal,VIndex)
VIndex = [VIndex(ib,1),VIndex(ib,2)]
>> size(Signal)
ans =
          2514           2
>> size(VIndex)
ans =
          2517           2
The problem with this, is that i am getting this following error :
Index exceeds matrix dimensions.
the issue is that the command that my ib is giving me something like this in the first columns :
   2572
    4004
    4
    5
    6
    7
    8
    9
    10
I would expect it to start with 4 and not the first 2 rows, thats why i am getting this error.
I removed the first 2 columsn manually, and it works well. But when executed, it keeps putting these 2 numbers in the first 2 rows…
Anyone encountered this?
Thank you
D

Probably you have used 'intersect' as a variable prior. Because I had the same issue and I searched my way to this thread. LOL. I rectified mine. I hope it helps someone in the future. Clear variable 'intersect'
