13.5 Call Stack

Command: dbstack
Command: dbstack n
Command: dbstack -completenames
Built-in Function: [stack, idx] = dbstack (…)

Display or return current debugging function stack information. With optional argument n, omit the n innermost stack frames.

Although accepted, the argument -completenames is silently ignored. Octave always returns absolute file names. The arguments n and -completenames can be both specified in any order.

The optional return argument stack is a struct array with the following fields:


The name of the m-file where the function code is located.


The name of the function with a breakpoint.


The line number of an active breakpoint.


The column number of the line where the breakpoint begins.





The return argument idx specifies which element of the stack struct array is currently active.
