Hi everyone,
Please, do you have any tips to automate indentation in scripts?

Please do not insert screenshots of code when text will suffice. It prevents us from copy/pasting the example.

Download my editorExtract and editorReplace tools,
https://www.mathworks.com/matlabcentral/fileexchange/181000-customized-text-modification-buttons-for-the-matlab-editor
Then add the function below as a Quick Access Toolbar button. You can then highlight the text you want to modify and apply the button to obtain text with all the "=" signs lined up.
function favoriteAlignEqualSigns()
[txt,info]=editorExtract(1);
before= char(extractBefore(txt,"="));
after = char(extractAfter(txt,"="));
newtxt=before+" = "+after;
editorReplace(newtxt,info);
end
Note that this function assumes one assignment statement per line of code (like in your example), and does no error checking to that effect.

I think that Matt's answer is a bit more elegant, although I think it (at least as first posted) just adds spaces before and after each equals sign rather than lining them up. I don't see anything that detects which column they should be aligned on. Here is a function which does do that.
% alignEquals.m
%
% Lines up the equals signs in the selected text in the active Matlab editor document.
function alignEquals()
ed = matlab.desktop.editor.getActive;
selected_lines = matlab.desktop.editor.textToLines(ed.SelectedText); % cell array containing the selected lines
eqIdx = strfind(selected_lines, '='); % find the index for all of the equals signs
maxeqIdx = max([eqIdx{:}]); % index of the farthest right equals sign
% align all of the equals signs with the farthest right equals sign
for iLine = 1:numel(selected_lines)
if isempty(selected_lines{iLine}), continue, end % skip empty lines
if isempty(eqIdx{iLine}), continue, end % skip lines with no equals sign
selected_lines{iLine} = strrep(selected_lines{iLine}, '=', [repelem(' ', maxeqIdx - eqIdx{iLine}) '=']);
end
newText = matlab.desktop.editor.linesToText(selected_lines); % selected text with the equals signs lined up
ed.Text = strrep(ed.Text, ed.SelectedText, newText); % replace the text in the editor document
end

Please, let me add an additionnal detail after using. Avoid "=" in comments. I changeet for ":" and everythings go good.
