Hello Bob,
Down at the bottom of the Embedded Coder page is a "Ready to Buy" section. If you click "Pricing and Licensing", you'll be taken to another page that has the option to request a quote.
You can see the other products required to use Embedded Coder on the System Requirements page. It requires MATLAB Coder at least. There are a few optional "requirements", like needing Simulink Coder if you would like to generate code from Simulink. Feel free to ask about whichever products you are interested in when you request the quote.
