UserModel = class UserModel(Model) |

UserModel(npars, userResult, ndim=1, userPartial=None, userDeriv=None,
userName='unknown', copy=None, **kwargs)
Wrapper for a Models where the User provides the method the evaluate
f( x: p ) as userResult( x, param )
and optionally the partial derivatives to p and x and a name
df/dp as userPartial( x, param )
df/dx as userDeriv( x. param )
name as string
Examples
--------
import numpy as np
>>> def ur( x, p ) :
>>> return p[0] * np.sin( p[1] * x + p[2] * np.log( x + p[3] ) )
>>>
>>>
>>> mdl = UserModel( 4, ur, userName="slowchirp" )
>>> print( mdl )
UserModel( slowchirp )
>>> print( mdl.npars )
4
