Emil, I think that TSInterpolate_RK is broken.
>From the manual page of TSRKRegister http://www.mcs.anl.gov/petsc/petsc-current/docs/manualpages/TS/TSRKRegister.html binterp is supposed to be a matrix but we are passing in the b vector in TSRKRegisterAll. Also, the NULL case for binterp is not taken into account. Could you please provide a fix in maint? Thanks, -- Stefano
