Hi,
i=1
j=2
I have a matrix A=[1 9
9 10
10 11
11 2]
I want to find out the first occurance of j in coloumn 2 after occurance of i in 1st coloumn at index idx.
i tried idx2 = find(A(idx:end, 2) == j, 'first') but it shows me error Second argument must be a positive scalar integer.
Help is much appreciated thanking in advance.

[~, ix1_2] = max(A == [ii, jj])

Hi Madhan,
Thanks for replying to my query. although it is a bit difficult for me to understand the answer. it would be great if you can give a bit elaborative answer in context to my question.
