Does Matlab have a function that provide label encoder for multi class classification ?

The Python's scikit learn library has a label encoder that encode target labels with value between 0 and n_classes-1 at the link below

Label Encoder

It also support the ability to transform labels back to the original version.

Does Matlab has an equivalent function ?

In the case matlab does not have it, is there anyway I can call this python encoder from matlab ?

I am using Matlab 2020a

For Classification problems, if you use Categorical variables, MATLAB will do this automatically for you. This is transparent to the user.

You can find more details about categorical variables here
