componentlist.isphysical - Function

1.4.2 Check if a component is physically plausible
Description

The isphysical function is used to check if the specified components meet a number of criteria that must be true if the component could be used to model a physical process. These criteria are:

The “Flux properties” section of the ComponentModels module documentation describes how it is possible to generate a component which has non-zero imaginary value in the Stokes representation.

It is possible to check a number of components at once by specifying the indicies of all the components. The returned value will only be True if all the specified components are physical.

Arguments

Example

      include ’componentlist.g’  
      cl := emptycomponentlist();  
      cl.simulate(2);  
      cl.setflux(1, [10, 1+3i, 1-4i, 0]print cl.isphysical(1:2), polarization=’linear’);  
      print cl.isphysical(1:2)
