Breakpoints in Anonymous Functions

There can be multiple breakpoints in an M-file line that contains anonymous functions. There can be a breakpoint for the line itself (MATLAB stops at the start of the line), as well as a breakpoint for each anonymous function in that line. When you add a breakpoint to a line containing an anonymous function, the Editor/Debugger asks exactly where in the line you want to add the breakpoint. If there is more than one breakpoint in a line, the breakpoint icon is blue .

When there are multiple breakpoints set on a line, the icon is always blue, regardless of the status of any of the breakpoints on the line. Position the mouse on the icon and a tooltip displays information about all breakpoints in that line.

To perform a breakpoint action for a line that can contain multiple breakpoints, such as Clear Breakpoint, right-click in the breakpoint alley at that line and select the action. MATLAB prompts you to specify the exact breakpoint on which to act in that line.

When you set a breakpoint in an anonymous function, MATLAB stops when the anonymous function is called. The following illustration shows the Editor/Debugger when you set a breakpoint in the anonymous function sqr in line 2, and then run the file. MATLAB stops when it runs sqr in line 4. After you continue execution, MATLAB stops again when it runs sqr the second time in line 4. Note that the Stack display shows the anonymous function.
