Dear All

I am fitting a line shape using TMinuit, MINOS, however, the results are always “STATUS=PROBLEMS” or “STATUS=FAILURE”.

I do not know how to optimize it.

Here is the code:

bes3plotstyle.h (5.9 KB)

bes3plotstyle.c (12.2 KB)

help1.cxx (14.1 KB)

help2.cxx (11.9 KB)

2

And there are also two codes:

bes3plotstyle.c (12.2 KB)

Here is another code need to repair:
help2.cxx (11.9 KB)
