Inmem List functions in memory.

M = INMEM returns a cell array of strings containing the names

of the M-files that are in the P-code buffer.

M = INMEM('-completenames') is similar, but each element of

the cell array has the directory, file name, and file extension.

[M,MEX]=INMEM also returns a cell array containing the names of

the MEX files that have been loaded.

[M,MEX,J]=INMEM also returns a cell array containing the names of

the Java classes that have been loaded.

Examples:

clear all % start with a clean slate

erf(.5)

m = inmem

lists the m-files that were required to run erf.

m1 = inmem('-completenames')

lists the same files, each with directory, name, and extension.

Managing the search path.

<path> - Get/set search path.

PATH Get/set search path.

PATH, by itself, prettyprints MATLAB's current search path. The initial

search path list is set by PATHDEF, and is perhaps individualized by

STARTUP.

P = PATH returns a string containing the path in P. PATH(P) changes the

path to P. PATH(PATH) refreshes MATLAB's view of the directories on

the path, ensuring that any changes to non-toolbox directories are

Visible.

PATH(P1,P2) changes the path to the concatenation of the two path

strings P1 and P2. Thus PATH(PATH,P) appends a new directory to the

current path and PATH(P,PATH) prepends a new directory. If P is already

on the path, then PATH(PATH,P) moves P to the end of the path,

and similarly, PATH(P,PATH) moves P to the beginning of the path.

For example, the following statements add another directory to MATLAB's

search path on various operating systems:

Unix: path(path,'/home/myfriend/goodstuff')

Windows: path(path,'c:\tools\goodstuff')

<addpath> - Add directory to search path.

ADDPATH Add directory to search path.

ADDPATH DIRNAME prepends the specified directory to the current

matlabpath. Surround the DIRNAME in quotes if the name contains a

space. If DIRNAME is a set of multiple directories separated by path

separators, then each of the specified directories will be added.

ADDPATH DIR1 DIR2 DIR3 ... prepends all the specified directories to

the path.

ADDPATH ... -END appends the specified directories.

ADDPATH ... -BEGIN prepends the specified directories.

ADDPATH ... -FROZEN disables directory change detection for directories

being added and thereby conserves Windows change

notification resources (Windows only).

Use the functional form of ADDPATH, such as ADDPATH('dir1','dir2',...),

when the directory specification is stored in a string.

P = ADDPATH(...) returns the path prior to adding the specified paths.

Examples

addpath c:\matlab\work

addpath /home/user/matlab

addpath /home/user/matlab:/home/user/matlab/test:

addpath /home/user/matlab /home/user/matlab/test

<rmpath> - Remove directory from search path.

RMPATH Remove directory from search path.

RMPATH DIRNAME removes the specified directory from the current

matlabpath. Surround the DIRNAME in quotes if the name contains a

space. If DIRNAME is a set of multiple directories separated by path

separators, then each of the specified directories will be removed.

RMPATH DIR1 DIR2 DIR3 removes all the specified directories from the

path.

Use the functional form of RMPATH, such as RMPATH('dir1','dir2',...),

when the directory specification is stored in a string.

P = RMPATH(...) returns the path prior to removing the specified paths.

Examples

rmpath c:\matlab\work

rmpath /home/user/matlab

rmpath /home/user/matlab:/home/user/matlab/test:

rmpath /home/user/matlab /home/user/matlab/test

<rehash> - Refresh function and file system caches.

REHASH Refresh function and file system caches.

REHASH with no inputs performs the same refresh operations that are done

each time the MATLAB prompt is displayed--namely, for any non-toolbox

directories on the path, the list of known files is updated, the list of

known classes is revised, and the timestamps of loaded functions are

checked against the files on disk. The only time one should need to use

this form is when writing out files programmatically and expecting

MATLAB to find them before reaching the next MATLAB prompt.

REHASH PATH is the same as REHASH except that it unconditionally reloads

all non-toolbox directories. This is exactly the same as the behavior of

PATH(PATH). This form should be unnecessary unless you are running

MATLAB in an environment where it is unable to tell that a directory has

changed. When this situation arises, MATLAB displays a warning upon

startup.

REHASH TOOLBOX is the same as REHASH PATH except that it unconditionally

reloads all directories, including all toolbox directories. This

form should be unnecessary unless you are modifying files in toolbox

directories.

REHASH PATHRESET is the same as REHASH PATH except that it also

forces any shadowed functions to be replaced by any shadowing functions.

REHASH TOOLBOXRESET is the same as REHASH TOOLBOX except that it also

forces any shadowed functions to be replaced by any shadowing functions.

REHASH TOOLBOXCACHE will update the toolbox cache file on disk.

Type "help toolbox_path_cache" for additional info.

<import> - Import packages into the current scope.

IMPORT Adds to the current packages and classes import list.

IMPORT PACKAGE_NAME.* adds the specified package name to the

current import list.

IMPORT PACKAGE1.* PACKAGE2.* ... adds multiple package names.

IMPORT CLASSNAME adds the fully qualified class name to the

import list.

IMPORT CLASSNAME1 CLASSNAME2 ... adds multiple fully qualified class

names.

IMPORT PACKAGE_NAME.FUNCTION adds the specified package-based function

to the current import list.

Use the functional form of IMPORT, such as IMPORT(S), when the

package or class name is stored in a string.

L = IMPORT(...) returns as a cell array of strings the contents

of the current import list as it exists when IMPORT completes.

L = IMPORT, with no inputs, returns the current import list

without adding to it.

IMPORT affects only the import list of the function within which

it is used. There is also a base import list that is used

at the command prompt. If IMPORT is used in a script, it will

affect the import list of the function which invoked the script,

or the base import list if the script is invoked from the

command prompt.

CLEAR IMPORT clears the base import list. The import lists of

functions may not be cleared.

Examples:

%Example 1: add the meta package of the MATLAB class system to

%the current import list

import meta.*

%Example 2: add java.awt package to the current import list

import java.awt.*

f = Frame; % Create java.awt.Frame object

%Example 3: import two java packages

import java.util.Enumeration java.lang.*

s = String('hello'); % Create java.lang.String object

methods Enumeration % List java.util.Enumeration methods

IMPORTING DATA

You can also import various types of data into MATLAB. This includes

importing from MAT-files, text files, binary files, and HDF files. To

import data from MAT-files, use the LOAD function. To use the

graphical user interface to MATLAB's import functions, type UIIMPORT.

For further information on importing data, see Import and Export Data

in the MATLAB Help Browser under the following headings:

MATLAB -> Programming Fundamentals

MATLAB -> External Interfaces -> Programming Interfaces

<genpath> - Generate recursive toolbox path.

GENPATH Generate recursive toolbox path.

P = GENPATH returns a new path string by adding all the subdirectories

of MATLABROOT/toolbox, including empty subdirectories.

P = GENPATH(D) returns a path string starting in D, plus, recursively,

all the subdirectories of D, including empty subdirectories.

NOTE 1: GENPATH will not exactly recreate the original MATLAB path.

NOTE 2: GENPATH only includes subdirectories allowed on the MATLAB

path.

Managing the java search path.

<javaaddpath> - Add directories to the dynamic java path.

JAVAADDPATH Add Java classes to MATLAB

JAVAADDPATH DIRJAR adds the specified directory or

jar file to the current dynamic Java path.

When loading Java classes, MATLAB always searches the

static Java path, defined in classpath.txt, before the

dynamic Java path. Enter 'javaclasspath' to see the

current static and dynamic Java path. Enter 'clear java'

to reload Java classes defined on the dynamic Java path.

Whenever the dynamic Java path is changed, 'clear java'
