====== New ======
###
ResponseFunction.New(Table) creates a new response function object according to the values in Table. Response functions can be of 4 different types (ListOfPoles, Tri, And, or Nat) and single-valued or matrix-valued. Below 8 examples for creating each of these response functions by hand at some arbitrary values.
###
===== ListOfPoles =====
###
Response functions stored as list of poles are defined via
$$ G(\omega,\Gamma) = A_0 + \sum_{i=1}^{n} B_{i-1} \frac{1}{\omega + \mathrm{i}\Gamma/2 - a_i} $$
###
==== Single valued functions ====
a = {10, -1,-0.5, 0, 0.5, 1, 1.5}
b = { 0.1, 0.1, 0.1, 0.1, 0.2, 0.3}
G = ResponseFunction.New( {a,b,mu=0,type="ListOfPoles", name="A"} )
print("The resposne function definition is")
print(G)
omega = 1.1
Gamma = 0.001
print()
print("Evaluated at omega =",omega," and Gamma =",Gamma," yields ",G(omega,Gamma))
Generates the output
{ { 10 , -1 , -0.5 , 0 , 0.5 , 1 , 1.5 } ,
{ 0.1 , 0.1 , 0.1 , 0.1 , 0.2 , 0.3 } ,
mu = 0 ,
name = A ,
type = ListOfPoles }
Evaluated at omega = 1.1 and Gamma = 0.001 yields (11.617645834991 - 0.011148328755289 I)
==== Matrix valued functions ====
