#SYNTAX FOR FOR LOOP IN MATLAB CODE#

Run each cell separately and follow the instructions, making sure that you also add in the required code marked by starred lines. > Complete the exercises in the script M-file for this week. > What happens when x equals to zero or x is not zero? % This code assigns the value of x to zeroValue only % if x is zero

If x What is wrong with the following code? Type it in MATLAB to check the error message. % This code assigns the value of x to negativeValue True if a is equal to 6 (note double equals sign) How many times will the starred line of the previous example be executed? What are starting point, increment (step) and ending point of this loop? S=0 % Initial assignment for sum to be able to Type in the following code and examine the output. While i Calculate the sum S of elements a i =√2i-1, i=1, 2. I=1 %we need to have a starting point to be able Now, let’s do the same by using while- loop Note: the command ‘ for i=1:1:10’ is equivalent to ‘ for i=1:10’.Note: the command ‘ for i=1:1:10’ does not create an array.The Syntax for for and while loops is as follows Else the hour of the day is not 6pm, print the statement “it is not dinner-time, it’s o’clock”. If the hour of the day is 6pm, print the statement “it is dinner-time, it’s o’clock”. In this case you do not know what will be your last number.Įxecutes a set of commands once, if a given condition is met, else- executes a set of commands, if the given condition is not met. In other words, while chronometer hand have not done a whole circle, keep counting. You are asked to count during one minute.

CommandĮxecutes a set of commands repeatedly by incrementing a variable by a given step size until the set maximum is reached.įor each hour from 1pm to 12pm, print the statement “it is o’clock”.Įxecutes a set of commands if a condition after while is true. The following table shows the main types. MATLAB offers features to allow you to control the sequencing of commands by setting conditions.

Understand the purpose of count variables.

Use if-else constructions to change the order of execution.

Create a while- loop to execute commands as long as a certain condition is met.Create a for- loop to repeatedly execute statements a fixed number of times.Use sequence controls- for, while, if-else.The index_variable can either be used in calculations inside of the loop if necessary or desired.Practical 4 For- and While- Loops, If-statements.That means you can check it to make sure that it worked the way that you expected it to. The index_variable persists in the workspace after the loop is completed.In the flowchart below this is what is meant by the true/false condition on the for loop diamond box. The loop is completed when the index_variable value is greater than or equal to the last_pass number.MATLAB will modify the index_variable by the increment amount specified at the start of each pass through the loop.If it is omitted, the increment will default to 1. for loops require 2 numbers to be defined: first_pass and last_pass.Do you have an idea for a way to calculate this in MATLAB?.THINK - You need to stop and think! You should be asking yourself these types of questions (and more!): Remember our mantra, think, sketch, code, test, repeat. In order for a computer to do it though, we need to transfer this process into an algorithm that can solve this problem for an arbitrary (n) number of terms. Imagine increasing our estimate to 20 terms! Whenever a process is tedious and repetitive, it is a perfect candidate to have a computer do it. Well, we can be sure that it will be more accurate but it is clear that the more terms that we add, the more tedious this process becomes.
