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.

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.
