Open you .m file in M-editor, move your cursor to a line and press F12. You will see a red dot in that line just left of the line number. You can click the place to turn on/off the break point too. Then press F5 to run the code. Click menu Debug for more options.

This merely puts in a breakpoint at the step. Now how do I run that step? Hitting F5 only continues with rest of execution of the code.

dbstep to execute one line.

dbstep in to step into a function being called on the current line.

To step though code while debugging use the buttons or commands shown in the documentation:

https://www.mathworks.com/help/matlab/matlab_env/keyboard-shortcuts.html

Because the keyboard shortcuts can be changed you should look these up on your installed MATLAB (see the link above). Try F10.
