Re: [julia-users] Linear convolution

I was worried about getting "a little noise in the result", so I ran a quick test in Matlab and Julia, and got almost exactly the same error. This is the Matlab code: Ts=0.01; t=-10:Ts:10; s=sinc(t); sc=Ts*conv(s,s); sc=sc(1000:3000); sum((sc-s).*(sc-s)) ans = 0.3695 So, at least for accura

Re: [julia-users] animated plot

Gaston supports output to GIF, which you could then assemble into an animation with an independent tool. https://github.com/mbaz/Gaston.jl If possible, use the development version -- the latest release is getting a bit long in the tooth. -- mb On Mon, Feb 24, 2014 at 11:57 AM, harven wrote:

Re: [julia-users] problem plotting with Gadfly/Cairo

Laksh, It works for me with julia 0.2 on Linux. I don't understand what this message means: INFO: Nothing to be done. You shouldn't see that message. Do you get the same thing when loading other packages? Can you delete or rename your .julia directory and try adding the package again? -- mb O
