According to the following page, MATLAB 2019a should have automatic singleton extension:

My tests show that this is not always true:
% A test array
>> x=false(3,3)
3×3 logical array
0 0 0
0 0 0
0 0 0
% Singleton extension works
>> x([1 3],2)=true
3×3 logical array
0 1 0
0 0 0
0 1 0
% Singleton extension doesn't work
>> x([1 3],2:3)=[true true]
Unable to perform assignment because the size of the left
side is 2-by-2 and the size of the right side is 1-by-2.

The linked blog post does not show assignment (=) included uder "Supported Operators and Functions." It still isn't:

OK, thanks. I will code around its absence. Pity, it would streamline the code.
