In such a case, the loop is most preferred as it reflects the common character of the particular loop. There might be some overlaps, such as executing the iterations until the specific numbers of loops or certain criterion do not reach. K = 1 while k <= 20 disp(k) k = k + 1 end Let’s compare two different codes in terms of while loop and for loop: for k = 1:20 disp(k) end When the user knows the number of iterations that will be done before the loop is started.Īt the same time, the While loop is much nicer in the case when the iterations need to be determined within the loop. There is a certain case in which the For loop is much nicer and more compatible. Output: Which is better to use for loop or while loop in Matlab? Syntax:“For” loop for m = 1:j for n = 1:k end End“While” loop while while end EndĮxample:Input: for a = 2:30 for b = 2:30 if(~mod(a.b)) break % if factor found, not prime end end if(b > (a/b)) fprintf(‘%d is prime\n’, a) end EndOutput: 2 is prime 3 is prime 5 is prime 7 is prime 11 is prime 13 is prime 17 is prime 19 is prime 23 is prime 29 is prime This can be done for ”while” loop or “for” loop statements. It is used to implement a single loop or more than one loop within other loops in Matlab. Example:Input: for b = disp(b) endOutput: 12 10 15 22 27 The batch of input valArray involves a cell, string, struct, or cell array. The loop will execute for the n times, where n is considered to be the number of columns for valArray, which is given by numel(valArray, 1, :). It is used to create an index of subsequent columns vector from a particular array, for instance: on the initial iteration, index = valArray (:, 1). Example:Input: for b = 1:10 fprintf(‘value of b: %d\n’, b) endOutput: value of b: 1 value of b: 2 value of b: 3 value of b: 4 value of b: 5 value of b: 6 value of b: 7 value of b: 8 value of b: 9 value of b: 10

This value function can be used to increase the index variable that is incremented by 1 from initval to endval, and this will repeat the execution of the code statements until the index has greater value than endval. Here, the values can be of any one kind among these three values that are listed below: initval:endval: Otherwise, the expression is considered to be false. When an expression is taken as true, then the result of it is nonempty, and it has the nonzero element that might be real or logical numeric.

It always checks the condition of the loop body before executing it.

It is used to repeat the number of statements or a statement when the given condition is true.
