Part 2. Basic looping 1. The for loop Ex. 14 Loop: Using for command b = 3; for k = 1:5 b end Output: 3 3 3 3 3 Remark: The blue-colored segment in lines 2-4 forms a "for-loop". The statement sandwiched between "for k = 1:5" and "end" is repeated 5 times, with the "k" index going from 1 to 5 step 1. Ex. 15 For loop: Utility of the dummy index b ...
For-Loop % loop a specific number of times, and keep % track of each iteration with an incrementing % index variable for i = 1:3 disp("cool"); end % control structures terminate with end While-Loop % loops as long as a condition remains true n = 1; nFactorial = 1; while nFactorial < 1e100 n = n + 1; nFactorial = nFactorial * n;
This MATLAB function evaluates an expression, and repeats the execution of a group of statements in a loop while the expression is true.
through the loop. A while loop executes a block of code an unknown number of times. Termi-nation is controlled by a logical expression, which evaluates to true or false. Here is the simplest while loop for our fixed point iteration. x = 3 while x ~= sqrt(1+x) x = sqrt(1+x) end This produces the same 32 lines of output as the for loop. However ...
while loop will continue until it is not. Consider the previous problem of squaring a vector element by element. A while loop to do so could look like: function [c]=ebyesquwhile(a) len=length(a);
While loop: The while loop repeatedly executes statements while a specified condition is true. Syntax Exp.1: Exp.2: heartrate = randi(200,1); if heartrate >= 100 disp ('PEEP DENGEROUS VERY HIGHT') elseif heartrate >= 90 disp ('HIGH HEART RATE') elseif heartrate >= 40 disp ('WELL') elseif heartrate >= 35 disp ('LOW HEART RATE') else disp ('PEEP ...
Loops are used to repeat sequences of calculations. In Matlab, loops can be implemented with a for ...end construct or a while ...end construct. In terms of their ability to repeat a series of calculations, for loops and while loops are equivalent.
