Re: [julia-users] mouse event

Hello colleague, i somehow agree, that the pieces are there - toolkits like Gtk/tk - datastructures like quadtrees or other spacial trees - drawing with cairo or GL like drawing - coordinate transformation - 'raw' plotting like Winston - your example of selection by box but

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

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.
