Debugging.

<debug> - List debugging commands.

DEBUG List M-file debugging functions

dbstop - Set breakpoint.

dbclear - Remove breakpoint.

dbcont - Resume execution.

dbdown - Change local workspace context.

dbmex - Enable MEX-file debugging.

dbstack - List who called whom.

dbstatus - List all breakpoints.

dbstep - Execute one or more lines.

dbtype - List M-file with line numbers.

dbup - Change local workspace context.

dbquit - Quit debug mode.

When a breakpoint is hit, MATLAB goes into debug mode, the debugger

window becomes active, and the prompt changes to a K>>. Any MATLAB

command is allowed at the prompt.

To resume M-file function execution, use DBCONT or DBSTEP.

To exit from the debugger use DBQUIT.

Overloaded methods:

mpc555_tgtaction/debug

Tools to locate dependent functions of an M-file.

<depfun> - Locate dependent functions of an M-file or P-file.

DEPFUN Locate dependent functions of a code file.

TRACE_LIST = DEPFUN(FUN) returns a cell array of files of the dependent

functions of FUN. To be analyzed, FUN must be on the MATLABPATH as

determined by the WHICH command. FUN is directly dependent on the functions

that it calls; FUN is indirectly dependent on the functions called by

the functions called by FUN, and so on. The files are analyzed and the

transitive closure done based on the information in the dispatcher.

The TRACE_LIST produced usually includes 'extra' files that would

never be called if FUN were actually evaluated. The files are listed

by the original arguments following by a list of additional

dependent files. Any duplicate argument files are dropped from the final

list. Script files can be included but the dependency analysis is

wildly conservative.

If the matlabpath contains 'relative' directories then any file in those

directories will have a 'relative' path.

Note: It cannot be guaranteed that DEPFUN will find every dependent file.

Some dependent files can be hidden in callbacks, or can be constructed

dynamically for evaluation, for example. Also note that the list of

functions returned by DEPFUN often includes extra files that would never

be called if the specified function were actually evaluated.

[TRACE_LIST, BUILTINS, MATLAB_CLASSES] = DEPFUN(FUN) also returns a

cell array of all builtin function names and MATLAB class names called

by FUN and its dependent functions.

The syntax for DEPFUN with all possible outputs is:

[TRACE_LIST, BUILTINS, MATLAB_CLASSES, PROB_FILES, PROB_SYMBOLS,...

EVAL_STRINGS, CALLED_FROM, OPAQUE_CLASSES] = DEPFUN(FUN)

where:

PROB_FILES is a structure array of M/P-files that DEPFUN could not parse,

locate, or access. Parsing problems can arise from MATLAB syntax errors.

The fields of the structure are:

.name - path to the file

.listindex - trace_list index

.errmsg - error message string

.errid - error id, if present

PROB_SYMBOLS [NOT IMPLEMENTED] is a structure array that indicates which

symbol names DEPFUN could not resolve as functions or variables. The

fields of the structure are:

.name - name of the symbol

.fcn_id - double array of trace_list indices

EVAL_STRINGS is a cell array of the files in TRACE_LIST that call eval

(or evalin, feval, fevalc, or evalc). These calls might use functions

that are not in TRACE_LIST.

CALLED_FROM is a cell array where each element is a double array and
