How can I instruct MATLAB editor to open a file with focus on specific line/function?

Hi,

I have a MATLAB class file in which i have implemented several methods. I am developing a UI around this using GUIDE and in the UI I would like the user to click on a particular method's name. Then Editor should open up the class and instead of having the 1'st line onwards in the view, the user should see the code from the test method onwards.

Is anyone aware of a way to achieve this? If so please share it.

The alternatives fread,fseek may work but a way to do this in the editor is what I am looking for.

Thanks!

This can be done using the editor api.

edit your_class.m
hEditor = matlab.desktop.editor.getActive;
hEditor.goToLine(line_number)

Awesome. Thanks a lot Sean for the quick reply!

Exactly what i was looking for.

P.S Also hEditor.goToFunction('function_name') goes to the exact function I need.

also you can do.

 matlab.desktop.editor.openAndGoToLine('fullpath and filename',linenumber)

for a single line.

oh and to go to specific function (without having to keep track of line numbers

 matlab.desktop.editor.openAndGoToFunction('full path and file name','function name')
