[Bug-gsl] DIFF in CSPLINE Interpolation bug !?

[Vijay Gopal Chilkuri]

Hi,

I did a test of CSPLINE interpolation from the GSL package and compared the
test (interp.c) file given in the doc/examples/ directory of the native GSL
package
to the XMGRACE interpolation function and found that they differ
significantly.
here i attach a pdf file which shows this difference.

I hope that there is an explanation for this , if so please help me
understand this
difference. The case in which this turns out to be a problem in the code I
would
like to help to correct this.

thanks a lot,
Vijay
