[mcstas-users] what happened to plane_intersect_Gfast?

[Peter Willendrup]

Dear Jean-Francois,


plane_intersect_Gfast was nothing but a special case of a second order equation solver (of course :-) ).

These days all comps needing this functionality apply solve_2nd_order instead, i.e.

Replace your existing 
ret = plane_intersect_Gfast(&dt, A, B, C); 

by 
ret = solve_2nd_order(&dt, NULL, A, B, C); 

in case you need only the first root of the polynomium. Alternatively send your component along here and I will have a look during next week. 


Best,

Peter
