问题 In the MatlabⓇ IDE, is there any easy way to jump to the definition of a particular method, without knowing in what class it is defined? For self-contained functions, I can type edit funcname.m . The same for classes. However, the hierarchy of superclasses for a particular class may be large.

问题 I am trying to run my python scripts in the command-prompt without calling python.exe first. I am specifically doing this in relation to running django-admin.py. I have C:\Python26 and C:\Python26\Scripts in my PATH. However, if I try running django-admin.py by doing: django-admin.py startproject helloworld I get the message: Type 'django-admin.py help' for usage.
