mongo function does not exist

>> server = "dbtb01";

>> port = 27017;

>> dbname = "mongotest";

>> conn = mongo(server,port,dbname)

Unrecognized function or variable 'mongo'.

I have MatLab 2020b installed as well as the Database Toolbox installed. Nothing I do seems to get the function to work - is there another path?

The reason for above error message is,

You would also need to install the additional Support Package for mongo DB connection, as explained in the following documentation page:

Database Toolbox is installed as suggested. Simply not working. Running on a Mac (Catalina).

[Monisha Nalluru]

Execute the following command

matlab.addons.installedAddons

Check if the list has "Database Toolbox interface for MongoDB"

In order to access Mongo Database from MATLAB. It need to have Database toolbox and Database Toolbox interface for MongoDB

Database Toolbox interface for MongoDB is a support pacakage present in add-ons.
