What a shame.

I am so sorry.

It looks like you are missing an argument.

When using argument "s", the function must not work with normalized frequencies, but with real radians/s.

The "sister" functions
- butt(...,"s")
- cheby1(...,"s")
- cheby2(...,"s")
work properly.

Testcase:

tWp = 1
tGp = -1
tWr = 2
tGr = -34
F = 10000000000000000
[n,Wn] = ellipord(tWp/F, tWr/F, -tGp, -tGr)
Wn *= F
[z,p,k] = ellip(n, -tGr, Wn, 's')

results in:
error: ellip: all elements of W must be in the range [0,1]

This message just makes sense in the absence of 's' parameter.
