gkernel(node, phinode, freqstep, scale, x.inc=1, x.min=node[1],
x.max=node[length(node)], plot=FALSE)

Arguments

node

values of the variable b for the nodes of the ridge.

phinode

values of the scale variable a for the nodes of the ridge.

freqstep

sampling rate for the frequency axis.

scale

size of the window.

x.inc

step unit for the computation of the kernel.

x.min

minimal value of x for the computation of Q_2.

x.max

maximal value of x for the computation of Q_2.

plot

if set to TRUE, displays the modulus of the matrix of Q_2.

Value

matrix of the Q_2 kernel
