Repeating yourself may frustrate you. This applies to programming. In some cases, a programmer must run a program multiple times.


The program runs the first statement, then the second, and so on. Control structures in programming languages allow complex programs to be executed. The same goes for “MATLAB For Loop”.


A programming language and multi-paradigm computer environment, MATLAB. Mathworks created it. MATLAB combines computation, visualization, and programming in an intuitive way. It’s all in equations.


To learn MATLAB “for” and “while” loop, read on. But first, let’s look at some MATLAB applications.






Mathematical computing environment Matlab The Matlab website says the environment is created for later usage.




Now let’s talk about MATLAB loops.


A loop statement allows a programmer to repeat a statement or a set of statements. The following flow diagram shows how MATLAB loops work:




How do Matlab loops help?


Loops allow you construct repetitive code and reduce repetitive code execution workload.


Suppose someone ordered you to count to 500 and then add 2. Start with 1, then move on to +2, then +2, and so on. This may be difficult for you as counting to 500 plus 2 is difficult for you.


In this scenario, Matlab loops are better. Loops are used to repeat a job. Loops have power. This is why most country sites programmers employ Matlab loops to simplify their work.


What are Matlab loops?


Matlab provides the following loops to handle the need to loop a statement. Let’s test them all in Matlab:


MATLAB loops


Matlab while loops


When the condition is true, it repeats the number of statements or a statement. It always examines the loop body’s state before running it.


while (expression) statements (end)


To be true, an expression must have a result that is nonempty and has a nonzero element that can be real or logical numeric. Otherwise, the expression is false.







b = 1


Values of b: 2 3 4


Value of b: 5


b = 7


b = 8


b = 9


Matlab loops


It abbreviates the program and manages the loop variable.


for index = values …end


The values can be any of the three values given below:




This value function can be used to increase the index variable from initval to endval by one, repeating the code execution until the index is greater than endval.




fprintf(‘value of b: percent dn’, b);end


b value: 1: 2: 3: 4: 5: 6: 7: 8: 9: 10:




Each repetition increases the index function by the step value, or decreases it if the step is negative.












It is used to build an index of subsequent columns vector from an array, for example: index = valArray (:, 1). The loop will run for n times, where n is the number of columns in valArray, supplied by numel (valArray, 1, :). This batch contains a cell, string, struct or cell array.

Matlab nested loops


Use it to create a single loop or several loops within a Matlab program. This can be done for while or for loops.


Syntax:“While” loopwhile expression1 while expression2; endEnd endEnd





2 is 1


3 is prime 5 is


7 is prime11, 13 is prime17, 19 is prime23, 29 is prime

In Matlab, should I use a for or while loop?


In some cases, the For loop is nicer and more compatible. When the user knows the number of iterations before the loop begins.


However, the While loop is more friendlier when the loop’s iterations need to be determined.


Let’s compare two separate while loop and for loop codes:


k = 1:20 disp(k);end k = 1;k = k + 1;end


Some overlaps may occur, such as executing iterations until a certain number of loops or condition is not reached. In this scenario, the loop is favored as it reflects the loop’s common character.


So, the user can use the “While” loop when unsure about the number of iterations. When the number of iterations is known, “For” loops are utilized.




Conditions for using While and For loops!







How do While and For loops differ in Matlab?


While Loop For Loop


/loop body for(initialization; condition; iteration)/For loop body




The loop’s top has merely initialization and condition checks.


These can be written at the loop’s top.




The while loop fails to compile if it contains no conditions.


The ‘for’ loop can simply iterate infinitely if no conditions are set up.




The while loop is used when the number of iterations is unknown.


The ‘for’ loop is used when the number of iterations is known.




If the while loop initializes during condition checking, it is finished every time the loop iterates.


The initialization step in the ‘for’ loop is never repeated.




The iteration statement can be written anywhere in the while loop.


The iteration statement appears at the top of the ‘for’ loop. So it will be run after the loop’s statements.


Control loops in Matlab


It is used to alter the normal sequencing. Whenever an operation exits a loop, the elements of the objects delete their scope. Matlab has two sorts of control statements:


Declare a

It ends a while or for loop in Matlab. Nothing after the break statement is executed. In nested loops, it comes from a specific endless loop. The statement’s control is transmitted to the loop’s end.









Values of b: 1 2 3 4




b = 5




This statement can control the next iteration in Matlab while or for loops. It’s also a break statement. Rather of forcing the loop to end, it proceeds on to the next iteration, skipping any code in between.






Ex: if b == 5 continue; fprintf(‘value of b: percent’, b);




b value 1: 2: 3: 4: 6: 7: 8: 9: 10:




While loops, for loops, and nested loops are all available in Matlab programming.


It also features two control statements: break and continue, which are used to regulate the looping of the statement in a program. Using loops to repeat certain statements can help shorten the final programmed program.
