rlTable using multiple element in rlFiniteSetSpec

Hi

I was tring to use Q-table in reinforcement learning toolbox. I have 3 signals in the obesrvation bus and used bus2RLSpec to create an 1x3 rlFiniteSetSpec for the observation. But when I created the rlTable using the following code.

qTable = rlTable(observationInfo,actionInfo);

I have the following error:

Error using rlTable/validateInput (line 131)

Input must be a scalar rlFiniteSetSpec

Error in rlTable (line 51)

validateInput(obj, ObservationInfo)

How should I change my observation object to work with rlTable or it's a limitation?

This is a current limitation with rlTable in MATLAB R2020a. To work with multiple observation channels, you can try a neural network representation instead. See rlQValueRepresentation.

Hi has this limitation been corrected by any chanche in 2021b?
