6 Editing and Debugging M-Files

Copying, Modifying, Disabling, and Clearing Conditional

Breakpoints

To copy a conditional breakpoint, right-click the icon in the breakpoint alley

and select Copy from the context menu. Then right-click in the breakpoint

alley at the line where you want to paste the conditional breakpoint and select

Paste from the context menu.

Modify the condition for the breakpoint in the current line by selecting

Set/Modify Conditional Breakpoint from the Debug or context men u.

Click a conditional breakpoint icon to disable it. Click a disabled conditional

breakpoint to cle ar it.

Function Alternative for Conditional Breakpoints

Use the dbstop function with appropriate arguments to set conditional

breakpoints from the Command Window, and use

dbclear to clear them. Use

dbstatus to view the breakpoints currently set, including any conditions,

which are listed in the

expression field. If no condition exists, the value in

the

expression field is [](empty). For details, see the function reference

pages:

dbstop, dbclear,anddbstatus.

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 bre ak point in a lin e, the brea k point

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 the breakpoint alley at
