MATLAB - Loop Types


Advertisements


There may be a situation when you need to execute a block of code several number of times. In general, statements are executed sequentially. The first statement in a function is executed first, followed by the second, and so on.

Programming languages provide various control structures that allow for more complicated execution paths.

A loop statement allows us to execute a statement or group of statements multiple times and following is the general form of a loop statement in most of the programming languages −

Loop Architecture

MATLAB provides following types of loops to handle looping requirements. Click the following links to check their detail −

Sr.No. Loop Type & Description
1 while loop

Repeats a statement or group of statements while a given condition is true. It tests the condition before executing the loop body.

2 for loop

Executes a sequence of statements multiple times and abbreviates the code that manages the loop variable.

3 nested loops

You can use one or more loops inside any another loop.

Loop Control Statements

Loop control statements change execution from its normal sequence. When execution leaves a scope, all automatic objects that were created in that scope are destroyed.

MATLAB supports the following control statements. Click the following links to check their detail.

Sr.No. Control Statement & Description
1 break statement

Terminates the loop statement and transfers execution to the statement immediately following the loop.

2 continue statement

Causes the loop to skip the remainder of its body and immediately retest its condition prior to reiterating.
