Research direction

Reproduce the crash by running docrun on the attached GasMixtureHome.md with GasMixture_lib.zip while Simulink and the library are initially closed. Start at the docrun handling for the MATLAB block and open_system call; done means the HTML page runs without crashing MATLAB in that startup condition.

Written by the indexing model from the issue text.

Description

Trying to set up a copy code block which opens a Simulink library.

docrun crashes MATLAB when running on this html page.

GasMixtureHome.md

GasMixture_lib.zip

Works if Simulink and the library are already open before calling docrun. Appears to be problem when library opening takes a long time i.e. Simulink not started.

Workaround currently to open library first.
