Hi all,

Where can I find the code for tabread4? Does someone have any lights on how this interpolation is implemented?

$ cd src/git/pure-data/src/ $ grep -l tabread4 *.c d_array.c $ vi d_array.c then

• • search for "tabread4_setup"
• • note that numbers are processed using the tabread4_float method
• • search for "tabread4_float" definition
• • study the algorithm

Right! I remember it now, so:

"a Lagrange interpolator"
