Hi,
I am fitting my data with 3 degree polynomial using poly_fit,
after running the program, im getting this warning message % POLY_FIT:
Warning: Invert detected a small pivot element. Please suggest me if
there is any way to get rid of this and why exactly im getting this
kind of warning.
Note: I read from poly_fit help that by setting the /double keyword,
we can get rid of this kind of warning. But that doesn't helped me.
regards
sid
