Matlab can't find geocradius function

Matlab is unable to compute the geocradius function. It says, "Undefined function or method 'geocradius' for input arguments of type 'double'".
Matlab actually recognizes the word as a function, even gives me help on it, but can't seem to use it. Is it possible my version doesn't have it even though the help browser references it? Can I download this function for free....or can someone email me the data array for geocradius(r), for r from 0 to 90 in a simple ascii file?
Thanks Chris

That function is part of the Aerospace Toolbox.
If you have the help information in your help browser, but it does not find the function, then my first suspicion would be that you have it installed but do not have a valid license for it. My second guess would be to execute
rehash toolbox
and see if that helped.

rehash did not work. I will take it into the administrator tomorrow and see if he can figure out.
Thanks

You can find out what Toolboxes are installed on your system by typing
ver
at the prompt.
It tells you all the mathworks products installed
If the Aerospace Toolbox doesn't show up in the list then you either have a problem with the licence / installation - or you dont have that toolbox.

Note that it might show up on the list if it is installed but you do not have the proper license. That can happen especially if you are licensed for a previous version but not the current version and you did a version upgrade rather than installing in a completely new directory.

So I've learned something. Thanks Walter.
