[Numpy-discussion] Re: Getting scipy.interpolate.pchip_interpolate to return the first derivative of a pchip interpolation

first derivative by 180/pi,  the interpolated first derivative coincides with the points for the cosine as expected. What I don't understand is how the interpolator came up with the scale factor it did and applied it using pure numbers. Any thoughts? Sam Dupree. On 1/21/23 18:04, Sam

this message, delete your original cf2py lines in the .for file and compile it all using $ f2py -c rkfn78.pyf rkfn78.for --fcompiler=gfortran --f77flags="-c -O -Wall" -m rkfn78 then you'll have no trouble with assumed-shape arrays. Cheers, Melissa On Mon, Oct 19, 2020 at 1

hat the callback FCN needs the dimension n as an argument. I was able to compile your code correctly after making these changes. If you have any further questions let me know, I hope this helps. Cheers, Melissa On Wed, Oct 14, 2020 at 4:03 AM Samuel Dupree <mailto:sdup...@speakeasy.net&g
