How to find the index in a row vector where a number exceeds a certain value?

I have a 1x600 row vector. The initial values are small and as we go towards the 200th element or so, the values start increasing. How can I find the exact index of the first element that exceeds a certain limit?

For example, I want to find the undex of the first element that exceeds the value of 50. In this case, it is the 187th element. How do I find that using a code?

Try :

A = 1:100;
lim = 50;
ind = find(A>lim,1); %% Here 1 after comma suggests the first element that is greater than 50

In the above case output should be ind = 51 For more info try

doc find

Hope this helps !

Worked perfectly! Thanks! I was missing the '1' for the first value.
