Matlab clear breakpoints in all files
After identifying a problem, end the debugging session. You must end a debugging session if you want to change and save an M-file to correct a problem or if you want to run other functions in MATLAB.
Note It is best to quit debug mode before editing an M-file. If you edit an M-file while in debug mode, you can get unexpected results when you run the file. If you do edit an M-file while in debug mode, breakpoints turn gray, indicating that results might not be reliable.
To end debugging, click the exit debug mode icon , or select Exit Debug Mode from the Debug menu. You can instead use the function dbquit to end debugging. When debugging a file that contains a loop, set the breakpoint inside the loop to examine the values at each increment of the loop. A conditional breakpoint causes MATLAB to pause at a specific line in a file only when the specified condition is met.
For example, you can use conditional breakpoints when you want to examine results after some iterations in a loop. To set a conditional breakpoint, right-click the gray area to the left of the executable line where you want to set the breakpoint and select Set Conditional Breakpoint. In the dialog box that opens, enter a condition and click OK.
When you run the code, MATLAB runs through the for loop twice and pauses on the third iteration at line four when n is 4. If you continue running the code, MATLAB pauses again at line four on the fourth iteration when n is 5 , and then once more, when n is 6. You also can set a conditional breakpoint programmatically using the dbstop function. For example, to add a conditional breakpoint in myprogram.
Setting error breakpoints is not supported in the Live Editor. Unlike standard and conditional breakpoints, you do not set error breakpoints at a specific line or in a specific file. MATLAB then enters debug mode and opens the file containing the error, with the execution arrow at the line containing the error. To set an error breakpoint, on the Editor tab, click Run and select from these options:. Pause on Warnings to pause on all warnings. Alternatively, you can set an error breakpoint programmatically by using the dbstop function with a specified condition.
You can set a breakpoint for the line itself and for each anonymous function in the line. To set a breakpoint on a line containing an anonymous function, click the gray area to the left of the line. MATLAB adds a breakpoint for the line, and a disabled breakpoint for each anonymous function in the line.
To set a conditional breakpoint, right-click the gray area to the left of the executable line where you want to set the breakpoint and select Set Conditional Breakpoint.

To enable a breakpoint for an anonymous function, click the disabled breakpoint for that function. To view information about all the breakpoints on a line, place your cursor on the breakpoint icon. A tooltip appears with available information. Line number in file specified as a character vector or string scalar. The default is 1. Line number in file , at the anonymous function number, specified as a character vector or string scalar.
For example, 1 2 specifies the second anonymous function on line number 1. If no anonymous function number is specified, then the default is 1. Name of a local function in file specified as a character vector or string scalar. If you want to clear a breakpoint set for a specific error, then specify the message id. For example:. If you want to clear a breakpoint set for a specific warning, then specify the message id. This condition has no effect when you disable warnings with the warning off all command or when you disable warnings for the specified message id.
For more information about disabling warnings, see warning. These errors occur when code returns an infinite value Inf or a value that is not a number NaN as a result of an operator, function call, or scalar assignment.
