Guys, I need help in my research.

I need to fit a x-y curve(200 points each)
in polymoninal to 9 degree or even 10 degree.

However, my IDL 4.01 on win 95 only allow me to fit

to 8 degree or less(just one degree less , isn't that great?)

9 degree or higher will cause the program to crash and jump out.

Both the poly_fit and polyfitw show the same thing.

I use a pentium 133 with 32 MB and IDL 4.01

would someone tell me that:

shold I pay for the IDL version 5

or should I put more memory into my computer or what ?

Please e-mail me at
