There is a public MATLAB Editor API. However, I cannot find any way to manipulate folding of m-source-code with code. I search something similar to the Editor Debug API (dbclear, dbcont, dbdown, dbquit, dbstack, dbstatus, dbstep, dbstop, dbtype).

On my wishlist is

store and restore of "the current folding state"
set folding line_number on/off
get folding line_number
and more

Currently, I may display the source code nicely with the help of folding. However, a search will unfold every block in which the string is found and the display is turned into a mess.

Thus, is there a backdoor to the folding functionalities?

在 MATLAB Online 中打开

I have not found a smarter way, but you could adopt the following solution, give that test.m contains:

for ii = 1:10
    s(ii) = 20;
end
for ii = 1:10
s(ii) = 20;
end

Open in the editor a give focus to previous document

current = matlab.desktop.editor.getActive;
edtObj  = matlab.desktop.editor.openDocument('C:\Users\ok1011\Desktop\test.m');
current.makeActive

Then smart indent everything and compare what got indented.

% Get unindented doc
txt         = matlab.desktop.editor.textToLines(edtObj.Text);
% Indent
edtObj.smartIndentContents;
txtIndent   = matlab.desktop.editor.textToLines(edtObj.Text);
% Line by Line comparison, true = unchanged, false = got indented
strcmp(txt, txtIndent)

The next step is to make a collage of the unindented code with the indented one, overwrite and save.
