Procedure from library finitediff.lib (see finitediff_lib).
- Usage:
- laxfrT(U1,U2,var); U1, U2 are the names of occuring derivatives, var is a variable in the basering;
- Return:
- type vector; gives a predefined approximation of the Lax-Friedrich-approximation for the derivation in the timevariable as often used in literature;
- Note:
- see also laxfrX, setinitials, scheme; Warning: laxfrT is not to be interchanged with laxfrX
