python - Put N points into M equal bins -


i have array n (positive) points. find m bin edges of histogram such bars have same height. in other words want find m+1 points such count of array points between 2 consecutive bin edges same.

example

>>> array = [0.3 0.3 0.3 0.7 0.8 0.9] >>> m = 2 >>> binpartition(array, m) [0, 0.5, 1]

i appreciate answer in python , numpy link known algorithm suffice! thank you! :)

than can done percentile:

import numpy np  def binpartition(array, m):     return np.percentile(array, np.linspace(0, 100, m + 1))  binpartition([0.3, 0.3, 0.3, 0.7, 0.8, 0.9], 2) >>> array([ 0.3,  0.5,  0.9])

i'm implementing inapp billing in android app. works well, however, i'm trying decouple broadcast receiver activity manifest. suggestion in android's trivialdrive sample: // important: dynamically register broadcast messages updated purchases. // register receiver here instead of <receiver> in manifest // because call getpurchases() @ startup, therefore can ignore // broadcasts sent while app isn't running. // note: registering listener in activity bad idea, done here // because sample. regardless, receiver must registered after // iabhelper setup, before first call getpurchases(). currently there's class extends broadcastreceiver : public class iabbroadcastreceiver extends broadcastreceiver { /** * intent action receiver should filter for. */ public static final string action = "com.android.vending.billing.purchases_updated"; private final iabbroadcastlistener mlistener; public iabbroadcastreceiver(iabbroadcastlistener listener) { m
