That is, the loop iterates for a number of times equal to the number of columns in A. For the first loop iteration, k is equal to A(:,1) for the second, k is equal to A(:,2) and so on until k equals A(:,n). Sets k equal to the vector A(:,i), where i is the iteration number of the loop.
You can often speed up the execution of MATLAB code by replacing for and while loops with vectorized code. For positive indices, execution terminates when the value of the index exceeds the end value for negative increments, it terminates when the index is less than the end value.įor example, this loop executes five times. You can specify any increment, including a negative one. The for loop executes a statement or group of statements a predetermined number of times. The continue and break statements give you more control on exiting the loop. The while statement is more suitable for basing the loop execution on how long a condition continues to be true or false. Use the for statement to loop a specific number of times. With loop control statements, you can repeatedly execute a block of code, looping back through the block while keeping track of each iteration with an incrementing index variable. Loop Control - for, while, continue, break Terminates the loop statement and transfers execution to the statement immediately following the loop.Ĭauses the loop to skip the remainder of its body and immediately retest its condition prior to reiterating.Loop Control - for, while, continue, break :: Basic Program Components (Programming) Programming Click the following links to check their detail. MATLAB supports the following control statements. When execution leaves a scope, all automatic objects that were created in that scope are destroyed. Loop control statements change execution from its normal sequence. You can use one or more loops inside any another loop. It tests the condition before executing the loop body.Įxecutes a sequence of statements multiple times and abbreviates the code that manages the loop variable. Repeats a statement or group of statements while a given condition is true. Click the following links to check their detail − Sr.No.
MATLAB provides following types of loops to handle looping requirements. Programming languages provide various control structures that allow for more complicated execution paths.Ī 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 − The first statement in a function is executed first, followed by the second, and so on. In general, statements are executed sequentially. There may be a situation when you need to execute a block of code several number of times.
