Put the cursor in the letters of a name of a function, like regiongrowing, and type control-d. This will display the code for the function in the code editor. It's similar to where you can put the cursor in variables and type control-d to being up the variable in the variable editor. In the source code for your function, you can set breakpoints and step through the code using the debugger to find any error or examine variables. See this link for more details: Debugging in MATLAB.
