Looks like I also need this feature.

I'm trying to design an second order Sallen-Key bandpass filter from [url=http://electronics.stackexchange.com/questions/215057/2nd-order-sallen-key-bandpass-filter-design-in-matlab this post], slightly modified version:

When trying to run this script:

I would be very appreciated for any info related to status of implementing of this functionality. Thanks!

Any progress on scheduling adding complex functionality to the control toolbox? Complex SYS math is a critical capability of Matlab that Octave does not support. At least tag the bug as confirmed since the code reports it as not yet supported.

@Mike How hard would it be to add this. I also need it.

Is there a schedule for complex number support in control pkg? The following works in both Matlab and Scilab but errors in Octave:

a=[1+i,0;0,1+i]
b=[.1;.2]
c=[0,.3]
d=[1]
myss=ss(a,b,c,d)

structures function with complex arrays, so it is unclear why the restriction.
