12 Dec 2014 Gauss-Jackson Eighth-Order ODE Solver (Fixed Step Size) Gauss-Jackson Eight-Order MultiStep Predictor-Corrector using ODE113 in its startup procedure. Author: Darin Koblick

Nice contribution.

One remark: number of states is hard-coded to 3.

Please replace these references to a variable number of states that you, for instance, can get from y0 at run time.

Thanks

Dear Matt,

tried calculating the intersection between a two triangles touching each other in a point but got following error.

Assume can be solved by setting tolerances correct?

Thanks

Christophe

Something's wrong. We should have found a recession vector (bb<0).

Exactly what I was looking for after first trying out Jos' submission. Unfortunately StrCmpFN on line 116 is undefined resulting in an error.

Well documented, elegant and efficient.

I agree on F Moisy comment from 2007. How do I use this witouth having to lose the date info when going down to hours and minutes?

Hi,

I need to zoom it to milli sec, but it happens only till second.
datetickzoom('x','HH:MM:SS.FFF');
Is there any way of doing it?

hold arrowkey -> matlab crashes

24 Jun 2010 PLOT4 Plot colored lines and points in 3-D space Author: Christophe Lauwerys Christian

Hey! Got a problem.
I have created a [X,Y,Z]=meshgrid(x,y,z) for my computed data corresponding to the x,y,z. lets say we have c(x,y,z)=data in a loop.
No i wanna distinguish the data field into a stable data and unstable data. So I want to plot in one plot the data points with a value of less or equal 1. I thought about setting it NaN case 1 and the other way round. But got an error msg.

Help is very welcome.
