Details:
Folks,
Attached is a file with code and output for a series of linear interpolations.
This runs about 600 times faster in Matlab. Not sure why. This emulates
part of a program I'm writing. I don't need to run in Octave but some of the
people I work with do.
I'm using an old version of Matlab:
MATLAB Version 7.1.0.246 (R14) Service Pack 3 (2005)
Maybe someone can speed things up?
BTW, I was one of the first contributors to Octave back in the early 90's.
Wrote the binary data interface.
