Detailed Description

a function that substitutes an argument with a value

afl::BasisArgument::BasisArgument ( size_t index )

Parameters:

index the i in u_i

virtual data_t afl::BasisArgument::evaluate ( const Point & p,

Function::Context * ctxt

) const [pure virtual]

evaluates the function
Parameters:

p the location to evaluate the function at

ctxt the context for the evaluation

Returns:
the value of the field at (x,y,z,t)
