GET Discovery Information

Description

Use the GET method to view information about the MATLAB^® functions that you deploy to the server. You receive information about

all deployed archives with discovery information.
names of the MATLAB functions that each archive contains.
names and MATLAB data types of the inputs and outputs for each of the MATLAB functions.
additional metadata.

If you build a deployable archive (CTF file) without including discovery information, it is not discoverable.

In order to use the discovery service, you must enable the discovery service on the server. Do this by uncommenting the option --enable-discovery in the main_config server configuration file.
