08 Jul 2009	bvp6c BVP ODE Solver Author: Nick Hale	Korzhenevych, Artem	Hello, I wonder if it is possible to use bvp6c with non-autonomous systems, namely in cases where the odefun is changing, depending on the time period. More specifically, I want to solve a two-point BVP, where one of exogenous parameters in ODEFUN changes at a certain time point. Does anyone have experience with this?
01 Dec 2008	bvp6c BVP ODE Solver Author: Nick Hale	HAN, Qun	Numerical calculation of the Jacobian consumes must of the computing time. If mex this section, the efficiency can be dramatically improved further.
04 Aug 2008	bvp6c BVP ODE Solver Author: Nick Hale	Hale, Nick	Sorry for the confusion. You should save the bvp6c folder somewhere on your system, then in MATLAB select File> Set Path> Add Folder> and then navigate to where you saved bvp6c.
21 May 2008	bvp6c BVP ODE Solver Author: Nick Hale	Liu, Joey	This package is really good, thanks alot. However, I do not know that why I encountered with problems when I was using this package. I did copy m-files to the MATLAB path. following are messages which MATLAB showed me. If you can help me, please contact me by the e-mail. I appreciate your kindness very much. ??? Undefined function or method 'odenumjac' for input arguments of type 'function_handle'. Error in ==> bvp6c>BCnumjac at 1321 [dBCdya,ignored,ignored1,nbc] = odenumjac(@bcaux,bcArgs,bcVal,dBCoptions); Error in ==> bvp6c>colloc_Jac at 966 [dGdya,dGdyb,nbc] = BCnumjac(bc,ya,yb,n,npar,nExtraArgs,ExtraArgs); Error in ==> bvp6c at 346 [dPHIdy,NF,NBC] = colloc_Jac(n,x,Xmid,Y,Ymid,yp,Fmid,ode,bc,Fjac,BCjac,npar,... Error in ==> FD_solve at 4 sol2 = bvp6c('ode_file_FD','bc_file_FD',solinit)
10 Apr 2008	bvp6c BVP ODE Solver Author: Nick Hale	Korzhenevych, Artem	Hello, I am sure that there is a typo on the line 486 of bvp6c. This part should read: if ~isempty(knownPar) sol.knownpars = [{knownPar(:)}]; end Otherwise, Matlab in unable to combine a vector and a structure if these appear to be elements of knownPar.

07 May 2009	Chebfun Numerical computation with functions instead of numbers.	John D'Errico	Thanks Tobin - that was what i was looking for. Those files are very readable, clearly explaining what a chebfun is and how to use them. I'll now call this a complete package. I've had the time to do a little more perusal of these tools now too. They work on my Mac, which is sometimes an issue.	5
