plot::Hatch is part of the MuPAD symbolic engine, and only operates in MuPAD notebooks. R2018a is the last release which will support MuPAD notebooks.

You were trying to use the call in MATLAB instead of in a mupad notebook.

There is no Mathworks routine to draw hatched plots. You can look in the File Exchange for some contributions that draw hatched plots.
