Re: [diagrams] Animation of heath evolution
I am now in the right track. Thanks for the help. By the way you can change avconv by ffmpeg.

Re: [diagrams] Animation of heath evolution
Hi
The function H t x takes two real numbers and return a real number. The
python program is attached. You can run it with "python heatsim.py"and it
produces
a mp4 file called "im5.mp4"
Thanks for the help
Jorge

Hello
I am trying to make a simulation of the evolution of the heath
using diagrams with animations. I can not find any example.
Could anybody tell me where can I find examples?
Any help is welcomed.
Thanks in advanced.
Jorge

Re: [diagrams] Animation of heath evolution
Hi Jorge, (I have sent this to diagrams-discuss again, let's keep the discussion on the mailing list so that others can also chime in if they have anything to add, or learn from whatever is said.) I am still not quite sure I am understanding what you want to do. What kind of function is H? I guess t is a real number? What type is x? And what type does H return? Maybe sending the python program as an attachment would be helpful (please also send clear instructions on how to run it). -Brent On Fri, Aug 10, 2018 at 2:56 PM Jorge Devoto wrote: > I have a function H t x, The variable t is time and the variable x denotes > ponts.

Re: [diagrams] Animation of heath evolution
Hi Jorge, I am not sure I understand what you mean by "evolution of the heath". Can you elaborate, or give an example? -Brent On Fri, Aug 10, 2018, 9:47 AM Jorge Devoto wrote: > Hello > > I am trying to make a simulation of the evolution of the heath > using diagrams with animations.
