Detailed Description

template<class Scalar>
class Thyra::DefaultAddedLinearOp< Scalar >

Concrete composite LinearOpBase subclass that creates an implicitly added linear operator out of one or more constituent LinearOpBase objects.

This class represents a added linear operator M of the form:

 
 M = Op[0] + Op[1] + ... + Op[numOps-1]
 
 

where Op[] is an array of numOps LinearOp objects. Of course the operator M is not constructed explicitly but instead just applies the constituent linear operators accordingly using temporaries.

In other words, this class defines apply() as:


 y = alpha*M*x + beta*y
   = alpha * ( Op[0]*x + Op[1]*x + ... * Op[numOps-1]*x ) + beta * y

 

Rather than calling the constructor directly, consider using the non-member helper functions described here.
