Command syntax for functions inside packages

Matlab has a "command syntax" where if you call a function without brackets the arguments are passed as character arrays to the called function, e.g.

help topic

is interpreted as

help('topic')

But this doesn't seem to work when the function is inside a +package folder - e.g. If I have

+mypack
|--myfunc.m

and I call

mypack.myfunc some arguments

This fails with:

mypack.myfunc some arguments
              ↑
Error: Invalid expression. Check for missing multiplication operator, missing or unbalanced delimiters, or other syntax error. To construct matrices, use brackets
instead of parentheses.

However, if I import the function it works fine, e.g.

import mypack.myfunc
myfunc some arguments

So the question is: Is command syntax supported for functions inside packages (without using import)? If so, how do I get it to work?

Hi Duc Le,

It is my understanding that command syntax is working fine when importing the package and then calling the function. But calling the function using the fully qualified signature is giving an error. Currently we are not supporting this feature.I have brought this issue to the notice of concerned people and it might be considered for future releases.

A possible workaround I would like to suggest is to make the package a normal folder and add it to the MATLAB path. With this approach, you can directly call the function using command syntax.

The following is the link to documentation of “addpath” to add the folder to the MATLAB path:
