Re: cs-lists, structure arrays ....

[Shai Ayal]

Thanks David and Stefan, your replies really helped me.

So to some it up, currently in octave, for a cs-list you can convert it to 
a vector or cell array by doing [list] and {list} respectively, so plotting 
all the heights in my fictitious data is as easy as

plot([data.height])

Thanks again,
        Shai


p.s. I will try to put this in the wiki
