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

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

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:

C:\Program Files\MATLAB\R2018b\toolbox\signal\signal\ellip.m
