Summary: This is a tutorial on using while loops in MATLAB.

Note: You are viewing an old version of this document. The latest version is available here.

The While Loop

The while loop is similar to the for loop in that it allows the repeated execution of MATLAB statements. Unlike the for loop, the number of times that the MATLAB statements in the body of the loop are executed can depend on variable values that are computed in the loop. The syntax of the while loop has the following form: 


while expression
    % MATLAB command 1
    % MATLAB command 2
    % More commands to execute repeatedly until expression is not true
end
where expression is a logical expression that is either true or false. (Information about logical expressions is available in Programming in MATLAB-Logical Expressions.) For example, consider the following while loop: 

n = 1
while n < 3
    n = n+1
end
This code creates the following output: 

n =

     1

n =

     2

n =

     3

Note that in all of this example, the MATLAB commands inside the while loop are indented relative to the while and end statements. This is not required by MATLAB but is common practice and makes the code much more readable.

My Favorites (?)

'My Favorites' is a special kind of lens which you can use to bookmark modules and collections directly in Connexions. 'My Favorites' can only be seen by you, and collections saved in 'My Favorites' can remember the last module you were on. You need a Connexions account to use 'My Favorites'.

Definition of a lens

Lenses

A lens is a custom view of Connexions content. You can think of it as a fancy kind of list that will let you see Connexions through the eyes of organizations and people you trust.

What is in a lens?

Lens makers point to Connexions materials (modules and collections), creating a guide that includes their own comments and descriptive tags about the content.

Who can create a lens?

Any individual Connexions member, a community, or a respected organization.

What are tags? tag icon

Tags are descriptors added by lens makers to help label content, attaching a vocabulary that is meaningful in the context of the lens.
