Dear friends,(adsbygoogle = window.adsbygoogle || []).push({});

I am a new member of physics forums, so this is may new message.

Already thanks to you for your helps to my question. I research some

applied mathematician problem's numerical solutions. There are initial-boundary value problems. I need an initial condition function which must be a periodic, continuous and

piecewise smooth type. Please vaiting for your suggestions.
