Description

Similar to poly2sym but can handle symbolic coefficients and indeterminate variables specified as equations.

SymPoly2Sym('a*x^2 + b*x + c','x') = [a b c]

SymPoly2Sym('a*sin(x)^2 + b*sin(x) + c','sin(x)') = [a b c]

Required Products

11 Apr 2004	Sarjoun Skaff	Enabled the manipulation of large expression without a problem.
16 May 2004	Peter Harrington	Crashes when given linear and constant terms. This bug can easily be fixed. Ax+b or b % causes the function to crash. It should be able to handle any level of polynomial include first and zero order. Works great for second order and higher
12 Jul 2005	Francisco Araya	It does not work for second order or less...
08 Aug 2006	Adrian Kaats	Nice!
30 Sep 2006	Babak Asghari	I found this function extremely useful for extracting coefficients of different variables in a large parametric expression. Thank u!
07 Dec 2006	Andreas Bogala	very useful! Thanks
03 May 2007	Patrick Vogelsang	That's what I needed!!
15 Jul 2008	Davide Costa	it is great!!! very very powerfull
