get array element

[Bryan.Fodness@gmail.com]

I have an array, and I would like to get the indice value.

a = array([13,14,15,16])

I would like something like a.getindice(15)

If I want 15 it would return 2

>>a = array('i', [13,14,15,16])
>>a.index(15)

2

You will want to ask numpy questions on the numpy mailing list. If you don't
mention that you are using numpy here, people get confused.

http://www.scipy.org/Mailing_Lists

Anyways, if your array is sorted, use a.searchsorted( 15). If it isn't sorted,
then you can find all of the indices equal to the value with the following:

In [7]: from numpy import *

In [8]: a = array([13,14,15,16])

In [9]: nonzero(a == 15)[0]
Out[9]: array([2])
