Possible bug in BP handling

Thanks. Yes indeed, I was jeopardized because when I originally tried it, it was not working -- and the reason for it was a SEGFAULT in my mex code. The current way, using the GUI to define the system's ODE and then manually change the odefile to include a user-supplied Jacobian works. A remark for whoever wants to try it: besides the definition of the @jacobian function passed to handle(3) of the output of the odefile, do not miss to include an opt=odeset('Jacobian',handles(3)); in the init function...

Derivatives from window

I cannot properly add the formulas for my jacobian matrix through the "from window" option. matcont produces the following chain of errors: Error using waitfor Undefined function or variable 'der_callback'. Error using uiwait (line 81) Error while evaluating UIControl Callback. Error using waitfor Undefined function or variable 'der_callback'. Error using uiwait (line 81) Error while evaluating UIControl Callback. This is both from the GUI and from the shortcut SysGUI.new. Note: my jacobian is provided...

Sorry, I found it out. There is no bug. The struct array of UserfunctionsInfo must be in the form 1 x n.

CL_matcont does not see multiple Userfunctions

Dear Hil, thank you for taking your time to reply. I am following up with some additional minor bugs, while I am running several continuations. -- Upon launching matcont by >> matcont from command line in MATLAB window, with matcont directory and subdirectories added to MATLAB path tree, unless I am inside the matcont directory, a long list of warnings is produced saying "Non existent directory" for all subdirectories in the matcont dir. -- Archive filter appears to have some fuzzy behavior. I cannot...
