MATLAB - The while Loop

The while loop repeatedly executes statements while condition is true.

Syntax

The syntax of a while loop in MATLAB is −

while <expression>
   <statements>
end

The while loop repeatedly executes program statement(s) as long as the expression remains true.

An expression is true when the result is nonempty and contains all nonzero elements (logical or real numeric). Otherwise, the expression is false.

Example

Create a script file and type the following code −

a = 10;
% while loop execution 
while( a < 20 )
   fprintf('value of a: %d\n', a);
   a = a + 1;
end

When you run the file, it displays the following result −

value of a: 10
value of a: 11
value of a: 12
value of a: 13
value of a: 14
value of a: 15
value of a: 16
value of a: 17
value of a: 18
value of a: 19
