Numpy solver : max value

I`ve got 2 variables :

period and result

How would I tell the Numpy solver ( I assume that's what I would have to use ) to return the period value that gives me the highest result ? Period has to be between 1 and 100 .

Edit :

Right now period at 14, gives me a result of 40 . period at 12 . gives me a result of 42 .

Can I tell numpy to try every period value between 1 and 100 and result only the one with the best result ?

I gu开发者_JS百科ess I don`t really need Numpy for that, I was wondering if it could be a way to go .

Just declare a variable equal to the period value of the first, then do your own loop, changing the initial variable any time the current number is bigger:

biggest = period(0)
index = 0

for i in range (1, 100)
    if period(i) > biggest
         biggest = period(i)
         index = i

return biggest

I am not certain i understand the question, but if i do then NumPy indexing might be best:

period = NP.arange(50)
result = NP.random.randint(1, 101, 50)

q = NP.argmax(result)   # gives index of largest value in the result array
result[q]               # returns the highest value in the result array
period[q]               # returns the value of period corresponding to 
                        # the highest value for result          

It's not clear what data you have, but this should work:

for period in periods:
    result = func(period)
    if result > resultmax:
        resultmax = result

or, if results is a numpy.array such that results[period] is the result from period, then simply

periodmax = results.argmax()
