Hello,
I was wondering if the find() function in C++ does the same as that done in MATLAB. In Matlab it is:
I = FIND(X) returns the linear indices corresponding to the nonzero entries of the array X.
Here's what I have to do:

lets assume R[10] = {1,0,2,3,0,9,0,4,5,6} is an array of 10 numbers and Length is 3.........
The Matlab expression is something like this:
index = find(abs(R(Length : Length * 2 - 1)) > 153) ;
Can anyone please tell me the implementation of this in C++.

Thanks,
Prads

The find function does not exist in C++, at least one that will perform the way you want it to - there is an algorithm named find from <algorithm>, but it will only return a single index, the first occurence of a given value within a range. To have a function that performs similarly to that in MATLAB, you would have to write your own.
