SAVE Save workspace variables to disk.
SAVE FILENAME saves all workspace variables to the binary “MAT-file”
named FILENAME.mat. The data may be retrieved with LOAD. If FILENAME
has no extension, .mat is assumed. Read More

quit

quit Quit MATLAB session.
quit terminates MATLAB after running the script FINISH.M,
if it exists. The workspace information will not be saved
unless FINISH.M calls SAVE. If an error occurs while
executing FINISH.M, quitting is cancelled. Read More

Manipulating Matrices

Matrices and Magic Squares

Matlab MatrisIn MATLAB, a matrix is a rectangular array of numbers. Special meaning is sometimes attached to 1-by-1 matrices, which are scalars, and to matrices with only one row or column, which are vectors. MATLAB has other ways of storing both numeric and nonnumeric data, but in the beginning, it is usually best to think of everything as a matrix. The operations in MATLAB are designed to be as natural as possible. Where other programming languages work with numbers one at a time, MATLAB allows you to work with entire matrices quickly and easily. A good example matrix, used throughout this book, appears in the Renaissance engraving Melancholia I by the German artist and amateur mathematician Albrecht Dürer. Read More

pack Consolidate workspace memory.
pack performs memory garbage collection. Extended MATLAB sessions may cause memory to become fragmented, preventing
large variables from being stored. pack is a command that saves all variables on disk, clears the memory, and then
reloads the variables. Read More

open

OPEN Open files by extension.
open NAME where NAME must contain a string, does different things
depending on the type of the object named by that string: Read More

clear

and from memory.
clear removes all variables from the workspace.
clear VARIABLES does the same thing.
clear GLOBAL removes all global variables.
clear FUNCTIONS removes all compiled M- and MEX-functions.

clear ALL removes all variables, globals, functions and MEX links.
clear ALL at the command prompt also removes the Java packages
import list. More »
