A "simple" question

From: Oriane Le Pocher on 22 Jun 2010 04:57 Hello! I've seen the following equation in a matlab file : T11 = simple(0.5*m1*v1.'*v1); And I was wondering what is the use of "simple" ? Thank you in advance for your answers.

Citation: A common problem with symbolic calculations is that the answer returned is often not in its simplest form. MATLAB's function 'simple' will perform all of the possible function manipulations and then return the one that is the shortest. Best wishes Torsten.

SIMPLE is a function from Symbolic Math Toolbox that attempts to find a short representation of a symbolic expression: http://www.mathworks.com/access/helpdesk/help/toolbox/symbolic/simple.html -- Steve Lord slord(a)mathworks.com comp.soft-sys.matlab (CSSM) FAQ: http://matlabwiki.mathworks.com/MATLAB_FAQ To contact Technical Support use the Contact Us link on http://www.mathworks.com
