Hi all, I think I have found the answer by further googling/refining the question.
In case others have similar question, below is the syntax from the Matlab's documentation itself.

You might want to have a look at the fill command as well - a bit more versatile

Thank you @David Fletcher 😊 for recommending an alternative to rectangle method, which looks me to a little bit more simple and more flexible as you said

Read about fill, patch. You need to have coordinates of the vertices.
Example:
% Vertices of rectangle
P = [0 0 ;0 1; 1 1; 1 0] ;
patch(P(:,1),P(:,2),'r','EdgeColor','k')
