Creating loops for repetitive statements is a great way of shortening the final code.
There are also specific loop control statements to control the execution of these loops.
For loops matlab code#
MATLAB allows using various types of loops in the code to handle looping requirements including: for loops, while loops and nested loops. Instead of forcing termination, ‘continue’ skips any code in between and forces the next iteration of the loop to be executed. The continue statement works comparable to the break statement. The continue command is used for giving control to the next iteration of the loop. The control then passes to the statement after the end of the loop. In the case of nested loops, break exits only from the loop in which it is encountered. Statements in the loop that are written after the break statement are skipped / not executed. The break command terminates execution of the for or while loop. These commands are similarly used in other programming languages too. MATLAB supports two specific loop control statements, the ‘break’ statement and the ‘continue’ statement. Most importantly, loop control statements are used to control the execution of the loop or to change execution from the normal sequence of commands.
For example, in a while loop, the comparative value(s) are defined before the loop initializes, whereas in a for loop the value conditions are defined when initializing the loop, in the for the statement. Control statements also direct the syntax of the loop. Loop Control Statements in MatlabĪ control statement is a combination of conditions that govern the body of the loop to execute until the specified condition becomes False. Notice how the structure changes using the while loop. The comparative value for the condition is defined before beginning the while loop, and the comparison condition is set in the while loop initialization.įor example, let us take the same condition as the first for loop example. The syntax for the while loop is as below.Ī condition is true when the result is not null and contains all nonzero elements (either logical or real numeric). The while loop will execute the statements repeatedly as long as the specified condition is true. The input valArray can be of any MATLAB data type, including a cell array, string, or struct. The loop executes for n times, and n is the number of columns of valArray, set by numel(valArray, 1, :). otherrowvector 4, 3, 5, 1, 2 for anyname otherrowvector display(. Generates a column vector index from successive columns of array valArray on each iteration. The for loop assigns a different element of this vector to the variable each run. Increases index by the value step on each iteration, or decreases when the step is negative.
