06 Aug 2009	Variable Precision Integer Arithmetic Arithmetic with integers of fully arbitrary size. Arrays and vectors of vpi numbers are supported. Author: John D'Errico	More fun with vpi2english if you use, for example, speak(vpi2english(vpi(2^52))) The function "speak" is summission File ID: #4769 named "Speak". There are a also a couple more "speak" submissions around.
31 Jul 2009	Fractions Toolbox create and manipulate fractions (K+N/D) using exact arithmetic Author: Ben Petschel	Very useful toolbox, especially with the added precision of the vpi toolbox. I think the demo_fr.m file needs an "echo on" at the beginning to see the header of each of the demo problems, rather than answers only (followed by echo off at the end).
31 Jul 2009	Fractions Toolbox create and manipulate fractions (K+N/D) using exact arithmetic Author: Ben Petschel	It seems to require vpi to be in the Matlab path, or a previous instance of a vpi. >> fr(1,7) ??? Error using ==> superiorto Unknown class 'vpi' listed in 'SUPERIORTO'. Error in ==> fr.fr at 201 superiorto('vpi','double','single','int8','uint8','int16', ...
29 Jul 2009	Variable Precision Integer Arithmetic Arithmetic with integers of fully arbitrary size. Arrays and vectors of vpi numbers are supported. Author: John D'Errico	Another good reason to use higher preciesion: the famous subtractive cancellation error >> x=77617;y=33096;z=33375y^6+100x^2(11x^2y^2-y^6-121y^4-2)+550y^8 z = -1.5112e+023 >> x=sym(77617);y=sym(33096);z=33375y^6+100x^2(11x^2y^2-y^6-121y^4-2)+550y^8 z = -200 >>x=vpa(77617);y=vpa(33096);z=100x^2(11x^2y^2-y^6-121y^4-2)+33375y^6+550y^8 z = -200.0 >> x=vpi(77617);y=vpi(33096);z=33375y^6+100x^2(11x^2y^2-y^6-121y^4-2)+550y^8 z = -200 vpi is as accurate as symbolic and vpa, roughly four times faster than sym and eight times faster than vpa
