get_par

Synopsis

Return a parameter of a model component.

get_par(par)

par - str

Example

Return the "c0" parameter of the "bgnd" model component and change it to be frozen:

>>> p = get_par('bgnd.c0')
>>> p.frozen = True

PARAMETERS

The parameter for this function is:

Return value

The return value from this function is:

par -- The parameter values - e.g. current value, limits, and whether it is frozen - can be changed using this object.
