    Description

    The haverdirect function creates a connection to a cloud instance of a Haver Analytics® database. Once you have created a haverdirect object, you can retrieve all historical data for a variable or historical data for a specific date range.

    From MATLAB®, you can retrieve data by following these steps:

    1. Create a Haver DLX Direct connection by using the haverdirect function.

    2. List variables by using the info function.

    3. Retrieve data by using the fetch function.
