GSL::Dht.alloc(size)
GSL::Dht.alloc(size, nu, xmax)
-
These methods allocate a Discrete Hankel transform object
GSL::Dht
of size size.
If three arguments are given, the object is initialized with the values of
nu, xmax.
GSL::Dht#init(nu, xmax)
-
This initializes the transform self for the given values of nu and xmax.
GSL::Dht#apply(vin, vout)
GSL::Dht#apply(vin)
-
This applies the transform self to the vector vin whose size is
equal to the size of the transform.
GSL::Dht#x_sample(n)
-
This method returns the value of the n'th sample point in the unit interval,
(j_{nu,n+1}/j_{nu,M}) X. These are the points where the function f(t) is
assumed to be sampled.
GSL::Dht#k_sample(n)
-
This method returns the value of the n'th sample point in "k-space",
j_{nu,n+1}/X.
GSL::Dht#size
-
Returns the size of the sample arrays to be transformed
GSL::Dht#nu
-
Returns the Bessel function order
GSL::Dht#xmax
-
Returns the upper limit to the x-sampling domain
GSL::Dht#kmax
-
Returns the upper limit to the k-sampling domain
GSL::Dht#j
-
Returns an array of computed J_nu zeros, j_{nu,s} = j[s]
as a
GSL::Vector::View
.
GSL::Dht#Jjj
-
Returns an array of transform numerator, J_nu(j_i j_m / j_N)
as a
GSL::Vector::View
.
GSL::Dht#J2
-
Returns an array of transform numerator, J_nu(j_i j_m / j_N).
GSL::Dht#coef
GSL::Dht#coef(n, m)
-
Return the (n,m)-th transform coefficient.
