ellip is missing from Matlab

missing function I'm looking for is call 'ellip

Is this a toolbox, can it be downloaded?

Answer 1

[Mark Sherstan]

If reffering to this function you need to install the signal processing toolbox.

[Nina Hunter]

Thank you Mark,

I already have that installed, is there anything else special that needs to be done?

Answer 2

It you aree certain that you have it licensed and installed, you may have path problems.

Run these lines (from a script or your Command Window):

restoredefaultpath 
rehash toolboxcache 

If the problem persists, use the Contact Us link in the upper right corner of this page to ask MathWorks for Technical Support. (Note: run the ver command first.)

If you have the Signal Processing Toolbox installed, then maybe you don't have a license for it, like your license expired, or you're in a shared pool of licenses where they've all been checked out.

What does this show?

which -all ellip
hasLicenseForToolbox = license('test','Signal_toolbox');	% Check for Signal Processing Toolbox.
if ~hasLicenseForToolbox
	% User does not have the toolbox installed, or if it is, there is no available license for it.
	% For example, there is a pool of 10 licenses and all 10 have been checked out by other people already.
	ver % List what toolboxes the user has licenses available for.
	message = sprintf('Sorry, but you do not seem to have the Signal Processing Toolbox.\nDo you want to try to continue anyway?');
	reply = questdlg(message, 'Toolbox missing', 'Yes', 'No', 'Yes');
	if strcmpi(reply, 'No')
		% User said No, so exit.
		return;
	end
end

You should see:
