# MATLAB - The while Loop - Tutorialspoint.

In many cases a for-loop can be replaced by an operation on a vector. This is generally more efficient and also results in briefer code. Two very useful commands are sum which calculates the sum of the elements in a vector, and prod which calculates the product of the elements in a vector. The syntax of a while loop in MATLAB is −. while end. The while loop repeatedly executes program statements as long as the expression remains true. An expression is true when the result is nonempty and contains all nonzero elements logical or real numeric. Step Five Loops: factorial Loops are a common thing to do in programming. If there is something you need to do over and over again, loops are the ticket. There are generally four types of loops. "for" loops, "while" loops, "do-while" loops, and finally recursion. Jul 03, 2018 · First let's have a brief idea of factorial using an example and then proceed for the program. Ex: Factorial of 5 = 5 4 3 2 1. So we can understand that we are decrementing the number until it becomes equal to ‘1’ and multiplying it with the previous result everytime ————- >statement 1. So, loops help us do such kind of things.

`Sep 21, 2018 · Figure 3: Number of loops. We can also use while loop as we used in the previous tutorial of sum calculation, its’ up to us which loop we prefer. If we are willing to multiply all previous number of a numeric integer which is the demand of factorial calculations we will need the previous product value of the loop.` Jan 04, 2015 · Then using while loop the value of ‘i’ is multiplied with the value of ‘f’. The loop continues till the value of ‘i’ is less than or equal to ‘n’.Finally the factorial value of the given number is printed.Step by Step working of the above Program Code:Let us assume that the number entered by the user is 6. Oct 24, 2015 · Home » MATLAB » Factorial of a number using Matlab. Saturday, 24 October 2015. Factorial of a number using Matlab. Saturday, October 24, 2015 function, MATLAB No comments Write a program to find the factorial of a given number using Matlab. Use the function name as factox, where x is the number. weave 2 while loop 2 xlabel 2.

Jul 26, 2017 · Code with C Programming: Projects & Source Codes › Forums › PHP › Find the factorial of 7 using for or while loop This topic has 1 reply, 1 voice, and was last updated 2 years, 4 months ago by CWC. Viewing 1 reply thread Author Posts July 26, 2017 at 10:07 am 12513 []. Jan 03, 2015 · Then using do-while loop the value of ‘i’ is multiplied with the value of ‘f’. The loop continues till the value of ‘i’ is less than or equal to ‘n’. Finally the factorial value of the given number is printed.Step by Step working of the above Program Code:Let. If you just want to get a result: math.factorialx While loop: def factorialn: num = 1 while n >= 1: num = num n n = n - 1 return num. Feb 09, 2014 · 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. Doing a factorial with only one while loop.for count = 9; count < 0; count-- means: start with count as 9; loop as long as count is smaller than 0; decrement count by one on each iteration. So you see, count < 0 should be count >= 0.

## Factorial of a Number in C using while Loop.

Use for loop or while loop to compute the factorial by using the below formula. 3. factn = n n-1 n-2. 1. 4. Display the result. Factorial of a number using while loop - Shell Script. The while loop it a lot more complex then the loop used for the previous step. Any help would be greatly appreciated. while mycosx - cosx <= threshold<--really not sure how to start and why I need to use.
