Identifier : ''

stack : 0-by-1 structure with fields: file, name, and line

This function depends on global state, and its programmatic use is not

encouraged. The new syntax,

try

execute_code;

catch exception

do_cleanup;

throw(exception);

end

should be used instead, where possible. At the command line,

MException.last contains all of the information in LASTERROR.

<lastwarn> - Last warning message.

LASTWARN Last warning message.

LASTWARN, by itself, returns a string containing the last warning message

Issued by matlab.

[LASTMSG, LASTID] = LASTWARN returns two strings, the first containing the

last warning message issued by MATLAB and the second containing the last

warning message's corresponding message identifier (see HELP WARNING for

more information on message identifiers).

LASTWARN('') resets the LASTWARN function so that it will return an empty

string matrix for both LASTMSG and LASTID until the next warning is

encountered.

LASTWARN('MSG', 'MSGID') sets the last warning message to MSG and the last

warning message identifier to MSGID. MSGID must be a legal message

identifier (or an empty string).

The WARNING function will update LASTWARN's state irrespective of

whether the warning invoked was on or off at the time.

See also warning, MException/last.

<disp> - Display array.

DISP Display array.

DISP(X) displays the array, without printing the array name. In

all other ways it's the same as leaving the semicolon off an

expression except that empty arrays don't display.

If X is a string, the text is displayed.

<display> - Display array.

DISPLAY Display array.

DISPLAY(X) is called for the object X when the semicolon is not used

to terminate a statement.

For example,

X = inline('sin(x)')

calls DISPLAY(X) while

X = inline('sin(x)');

does not.

A typical implementation of DISPLAY calls DISP to do most of the work

and looks as follows. Note that DISP does not display empty arrays.

function display(X)

if isequal(get(0,'FormatSpacing'),'compact')

disp([inputname(1) ' =']);

disp(X);

else

disp(' ');

disp([inputname(1) ' =']);

disp(' ');

disp(X);

end

<intwarning> - Controls the state of the 4 integer warnings.

INTWARNING Controls the state of the 4 integer warnings.

The 4 integer warnings are:

MATLAB:intConvertNaN

MATLAB:intConvertNonIntVal

MATLAB:intConvertOverflow

MATLAB:intMathOverflow

INTWARNING will be removed in a future release.

Interactive input.

<input> - Prompt for user input.

INPUT Prompt for user input.

R = INPUT('How many apples') gives the user the prompt in the

text string and then waits for input from the keyboard.

The input can be any MATLAB expression, which is evaluated,

using the variables in the current workspace, and the result

returned in R. If the user presses the return key without

entering anything, INPUT returns an empty matrix.

R = INPUT('What is your name','s') gives the prompt in the text

string and waits for character string input. The typed input

is not evaluated; the characters are simply returned as a

MATLAB string.

The text string for the prompt may contain one or more '\n'.

The '\n' means skip to the beginning of the next line. This

allows the prompt string to span several lines. To output

just a '\' use '\\'.

<keyboard> - Invoke keyboard from M-file.

KEYBOARD Invoke keyboard from M-file.

KEYBOARD, when placed in an M-file, stops execution of the file

and gives control to the user's keyboard. The special status is

indicated by a K appearing before the prompt. Variables may be

examined or changed - all MATLAB commands are valid. The keyboard

mode is terminated by executing the command RETURN (i.e. typing

the six letters R-E-T-U-R-N and pressing the return key). Control

returns to the invoking M-file.

DBQUIT can also be used to get out of keyboard mode but in this case

the invoking M-file is terminated.

The keyboard mode is useful for debugging your M-files.

Abstract superclasses.

<handle> - Superclass of all handle classes.

HANDLE Superclass of all handle classes.

A handle is an object that indirectly references its data. When a

handle is constructed, an object with storage for property values is

created. The constructor returns a handle to this object. When a

handle object is copied, for example during assignment or when passed

to a MATLAB function, the handle is copied but not the underlying

object property values.

The HANDLE class is an abstract class and cannot be directly

constructed. It is the superclass for all classes that follow handle

semantics.

Classes that define events must be handle classes (i.e., they must be

derived from HANDLE). Classes that are derived from the built-in

classes HGSETGET or DYNAMICPROPS become handle classes. When defining

a class that inherits from two or more super-classes simultaneously,

all superclasses must be handle classes or none can be. A derived

class cannot inherit from both handle and value classes simultaneously.

Classes that are derived from HANDLE inherit no properties, but do

inherit the following methods which can be overridden as needed.

handle methods:

addlistener - Add listener for event.

delete - Delete a handle object.

eq - Test handle equality.

findobj - Find objects with specified property values.

findprop - Find property of MATLAB handle object.

ge - Greater than or equal relation.

gt - Greater than relation.

isvalid - Test handle validity.

le - Less than or equal relation for handles.

lt - Less than relation for handles.

ne - Not equal relation for handles.

notify - Notify listeners of event.

<hgsetget> - HG-style set and get for MATLAB objects.

HGSETGET HG-style set and get for MATLAB objects.

The hgsetget class is an abstract class that provides an HG-style

property set and get interface. hgsetget is a subclass of handle, so

any classes derived from hgsetget are handle classes.

classdef MyClass < hgsetget makes MyClass a subclass of hgsetget.

Classes that are derived from hgsetget inherit no properties but

do inherit methods that can be overridden as needed.

HGSETGET methods:

set - Set MATLAB object property values.

get - Get MATLAB object properties.

setdisp - Specialized MATLAB object property display.

getdisp - Specialized MATLAB object property display.

<dynamicprops> - Support for dynamic properties.

DYNAMICPROPS Support for dynamic properties.

The DYNAMICPROPS class is an abstract class that provides support

for dynamic properties for MATLAB objects. Dynamic properties can

be used to attach temporary data to MATLAB objects.

classdef Myclass < dynamicprops makes 'Myclass' a subclass of

dynamicprops, which is a subclass of handle.
