c# - How to XML serialize child class with its base class -

-

i able serialize single type/class there way can serialize base class too?

for example:

class b:a

here able serialize class b how can serialize class ?

a must know in advance, i.e.

[xmlinclude(typeof(b))] public class {...}   public class b {...}

now new xmlserializer(typeof(a)) can serialize a or b. can without attributes passing in extratypes parameter overloaded xmlserializer constructor, again - root should a; i.e. new xmlseralializer(typeof(a), new[] {typeof(b)})

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,
