ell1mag(1)

NAME
ell1mag - magnitude of elliptic filter

CALLING SEQUENCE
[v]=ell1mag(eps,m1,z)

PARAMETERS

eps : passband ripple=1/(1+eps^2)

m1  : stopband ripple=1/(1+(eps^2)/m1)

z   : sample vector of values in the complex plane

v   : elliptic filter values at sample points

DESCRIPTION
Function used for squared magnitude of an elliptic filter. Usually m1=eps*eps/(a*a-1).
