as fast as promised

02 Jan 2014 Fast 2-dimensional interpolation Provides a 5x-50x speedup over interp2 Author: Nathaniel Brahms Karimi, Davood

Thank you for sharing this code. I really need a fast 2D interpolation function for my work; but my tests show that this code is even slightly slower than Matlab's interp2. Am I making a mistake in using this?

15 Nov 2013 Fast 2-dimensional interpolation Provides a 5x-50x speedup over interp2 Author: Nathaniel Brahms Crapeau, Marc

On R2012a, for very small interpolations (2x2 matrices interpolated in 1 point), speed up by a factor 10!

15 Oct 2013 Fast 2-dimensional interpolation Provides a 5x-50x speedup over interp2 Author: Nathaniel Brahms Eric

My testing indicates this is slower than interp2 for Matlab R2013a.

I am using optimization and need to interpolate for each iteration. This sped the process up over 60x faster than using interp2 and gives the same results. Thanks!!!
