Create documenation for custom toolbox

I'm writing a toolbox right now with own functions and want to create a documenation in html for it.

My Matlab version is 2018b.

I'm writing the function description into the head of my m-file.

Example:

%% BINTOMAT  Converts .BIN /.HEAD CATR Data into .mat file.
% |binToMat()| opens a File-Selector GUI to select .BIN /.HEAD files.
% Created .mat-file will placed into the same path.
%
% |binToMat('path\to\files')| opens a File-Selector GUI at the given path to
% select .BIN /.HEAD files. Created .mat-file will be placed into the 
% same path.
%
% |binToMat('path\to\files','ALL')| creates the .mat-file directly without
% opening a GUI.
%
%% Notes:
% ...
%
%% Examples:
% ...
%
% See also ASYSOL_CSV_TO_EXCEL_CIRCULAR_CO_CX, ASYSOL_TO_EXCEL_LINEAR_CO_CX

As you can see I use markup style to have a nice output.

I tried 3 methos to create a documenation from it:

1 . publish(m-file) and view output html-file.

2. save m-file as mtx-file and use matlab.internal.liveeditor.openAndConvert(mtx-file, 'output.html'). View output html-file.

3. save m-file as mtx-file and use doc functionname

The created output styles of 1. and 2. are different. (I prefere 2.. Is there a way of creating a mtx-file programmaticaly (matlab.internal.richeditor.openAndSave doesnt work in my matlab version))

Do I miss a method to create a documentation?

Is there a way to create the third output from a m-file programmaticaly?
