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 ...
Part 1. Write your first Matlab program Ex. 1 Write your first Matlab program a = 3; b = 5; c = a+b Output: 8 Remarks: (1) The semicolon at the end of a statement acts to suppress output (to keep the program running in a "quiet mode"). (2) The third statement, c = a+b, is not followed by a semicolon so the content of the variable c is "dumped ...
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;
15 gru 2022 · There is no 1-to-1 correspondence to the C++ do while loop in MATLAB. Your best option is to use a while loop. The difference is that while loops check the condition at the beginning of the loop while do while loops check the condition at the end of the loop.
function [c]=ebyesquwhile(a) len=length(a); ii=1; while ii<=len c(ii)=a(ii)^2; ii=ii+1; end. For a while loop, the index was initialized before the while loop began. The loop compares ii and len, finds that the statement is indeed true, so it calculates c and increments the index by one.
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.
2. while loops Create and run a script file with the following commands to see an example of how a while loop works. This script asks for a positive number a as input and estimates √ a using Newton’s Method. Newton’s Method applied to the function f(x) = x2 −a produces a sequence of numbers x1,x2,x3,...that converges to a root of f.
