czt(1) Scilab Function czt(1)
NAME
czt - chirp z-transform algorithm
CALLING SEQUENCE
[czx]=czt(x,m,w,phi,a,theta)
PARAMETERS
x : input data sequence
m : czt is evaluated at m points in z-plane
w : magnitude multiplier
phi : phase increment
a : initial magnitude
theta : initial phase
czx : chirp z-transform output
DESCRIPTION
chirp z-transform algorithm which calcultes the z-transform on a spiral in
the z-plane at the points
[a*exp(j*theta)][w^kexp(j*k*phi)] for k=0,1,...,m-1.
