Re: [Jsbsim-matlab] Matlab Crash

[Agostino De M. <ago...@un...>]

Alan,

which version of Matlab are you using?
Did you use the S-function (and the rest of all files)
as-is?

Please, do keep in mind that the latest version of JSBSim
doesn't fit with the S-function code.
When Brian and I implemented that code the JSBSim
logic that propagates aircraft state variables used to
be a little bit different.

The current version of the S-function code should be revamped
in order to work nicely with the recent modifications of
JSBSim.

Moreover, I had to compile the S-function with MS Visual Studio 2008.
The VS2010 had problems with some headers of Matlab (mostly becaause
of redefinitions of math functions).
