Shift current workspace to workspace of caller, while in debug mode
This function allows you to examine the calling MATLAB® code file to determine what caused the arguments to be passed to the called function.
dbup changes the current
workspace context, while the user is in the debug mode, to the workspace
of the calling file.
dbup functions change the workspace
context to each previous calling file on the stack until the base
workspace context is reached. (It is not necessary, however, to move
back to the current breakpoint to continue execution or to step to
the next line.)
If your receive an error message such as the following, it means
that the parent workspace is under construction so that the value
x is unavailable:
