How do I set a starting point in a find function

Hi,

I want to find the first value in a array after a specific rownumber.

Eg:

A = [3; 6; 2; 3; 1; 7];

[a b] = find(A >= 4,1,'first');

here the function will find a=2, b=1, but I want to start the find function at this specific point.

Is it possible to set a starting point for the find-funktion?

Greetings

Benni

If you know you wanted to start the search at a known row and column index you could use

iStart = 2
jStart = 3
[a,b] = find(A(iStart:end,jStart:end)>=4,1,'first')
