Hi Everyone
I think I'm missing something really obvious but what I would like to
do is extract the indexes from an array where a number matches - For
example
data = [0,1,2,960,5,6,960,7]
I would like to know, for example the indices which match 960 - i.e.
it would return 3 and 6
I could do this with a loop but I was wondering if there was a built
in numpy function to do this?
BTW if anyone is interested I'm converting some idl code to numpy and
trying to mmic the IDL function where
Cheers
Ross
