parameters¶
These are the fit parameter objects. They store the name, the value and the error of each parameter and are used in various fitting tools.
- class LT_Fit.parameters.Parameter(value, name='var', err=0.0)¶
Define a parameter as follows:
>>> import LT_Fit.Parameter as P >>> mypar = P.Parameter(0.) >>> mypar = P.Parameter(0., 'my_first_parameter') >>> mypar = P.Parameter(0., name = 'my_first_parameter') >>> mypar = P.Parameter(0., name = 'my_first_parameter', err = 0.1)
Other possible operations:
>>> mypar() # if the parameter is called it returns it's current value only >>> mypar.get() # returns the tuple (name, value, error) >>> print(mypar) # print a string representation of the name, value and error
- get()¶
return the current value
- set(value, name=None, err=None)¶
Set the value of a parameter:
>>> mypar.set(50.) # this value is now 50
