Hello all, On several occasions, I've had the need to find only the first occurrence of a value in an unsorted numpy array. I usually use numpy.where(arr==val)[0] or similar, and don't worry about the fact that I'm iterating across the entire array.
However, sometimes the arrays are pretty big and the find operation is in an inner loop, so I was wondering if there's already a C extension function somewhere in numpy or scipy that does a fast find first operation, or anything similar. (Easy enough to write my own, and maybe given the issues inherent in comparing float equality, etc., it doesn't belong in the core numpy anyway...)
