cross platform - Library that would work on Mac, PC and that can also be ported on mobile devices -

-

i'm going building library processing , generating syncml messages (syncml = xml protocol syncing contacts , calendars), , i'd able port , use library on many devices possible (mac, pc, iphone, android, blackberry, windows phone 7), because logic going same, , don't want spend time on re-building native library each platform.

my question is: technologies , programming languages should getting done? java, c , c++ spring mind, , colleague has suggested lua. i'd so's opinion on before start working on it.

my background c#/.net, objective-c, , java.

any information welcome. thank you!

why reinvent wheel? java has runtime environment mac, pc, linux, android, blackberry, , windows mobile. unfortunately popular option, iphone, has propriatary coding platform , can't run java.

java has done hard work in writing cross-platform runtime environment. careful version of java platform use though, mobile devices may not support newest se yet.

with objective-c , c# .net background, java should childs play pick up.

i want make logharitmic fit. keep getting runtime error: optimal parameters not found: number of calls function has reached maxfev = 1000 i use following script. can tell me go wrong? use spyder still beginner. import math import matplotlib mpl scipy.optimize import curve_fit import numpy np #data f1=[735.0,696.0,690.0,683.0,680.0,678.0,679.0,675.0,671.0,669.0,668.0,664.0,664.0] t1=[1,90000.0,178200.0,421200.0,505800.0,592200.0,768600.0,1036800.0,1371600.0,1630800.0,1715400.0,2345400.0,2409012.0] f1n=np.array(f1) t1n=np.array(t1) plt.plot(t1,f1,'ro',label="original data") # curvefit def func(t,a,b): return a+b*np.log(t) t=np.linspace(0,3600*24*28,13) popt, pcov = curve_fit(func, t, f1n, maxfev=1000) plt.plot(t, func(t, *popt), label="fitted curve") plt.legend(loc='upper left') plt.show() your original data t1 , f1 . therefore curve_fit should given t1 second argument, not t . popt, pcov = curve_fit(func,
