[julia-users] Equivalent of Matlab zpk()?

[Joe Tusek]

I've been translating some Matlab code for calculating a
spectral optimisation function that uses Matlab's zpk() function and I
can't find an equivalent in Julia packages. The DSP.jl looks like its a
start on a well appointed package but is a bit thin at this stage. Is there
anything out there than can be substituted for zpk()? Control.jl looks
like a start also but is not published.

Depending how your filter is represented, zpkdata from Control.jl might be
a good choice - i'm not using it, but the code looks promising.
