[PD] Fwd: Sinesum, cosinesum and cubic interpolation's guard points

2013-09-06 Thread Alexandros Drymonitis
Ok, but why don't you need the guard points at the end of the array when you're using [tabread4~], and only the first guard point? In the audio examples of Pd's browser, the patch B04.tabread4.interpolation.pd demonstrates the use of the object where it reads an array of 11 elements, from index 1

The read points actually rangee from 1 to 9 (or 8.9 - something) - and if, for nstance, you want to read teh value at 8.5, you need the points 7, 8, 9, and 10. So teh sze is 11 (indices 0-10 nclusve). It's confusing, I know cheers Miller On Fri, Sep 06, 2013 at 01:53:54PM +0300,

I understand this, I understand how cubic interpolation works, to some extent. What I don't understand is in what way is this different to the way [tabosc4~] deals with tables. If I want to feed a table with values from a mathematical function, should I copy the last element to index(0) and the
