When I try to run a simple plot script, I get the following error?

Hi,

You can try a couple of things to fix it:.

1.Type the following command in MATLAB command prompt to see if you have the connector installed:

which -all connector

2. If you don't see any connectors installed, run MATLAB as administrator and install the connectors.

3. Also there may be a possibility that the path to the connector folder is not added, try adding it manually.
