This document discusses loops in MATLAB. It begins with an introduction to loops, explaining that they are used to repeatedly execute a block of code until a condition is met. It then covers the basic structure of loops and the different types of loops in MATLAB - for loops, while loops, and nested loops. The document provides syntax examples for for and while loops. It also compares while and for loops. Finally, it poses several programming exercises involving loops, such as calculating the Fibonacci series, checking if a number is palindrome, perfect, prime, etc.

- 1. MATLAB Looping Control Statements CS-5 By: Prof. Ganesh Ingle
- 2. Course Main Topic/Chapters Introduction Overview of Loop statement For loop While loop Nested loop While loop vs for loop
- 3. Introduction A loop is used for executing a block of statements repeatedly until a particular condition is satisfied. For example, when you are displaying number from 1 to 100 you may want set the value of a variable to 1 and display it 100 times, increasing its value by 1 on each loop iteration.

- 5. Basic Structure of a Loop Statement A loop is used for executing a block of statements repeatedly until a particular condition is satisfied.
- 6. Types of Loops Loops are of 2 types: Entry-controlled and exit-controlled. 'C' programming provides us 1) while 2) for loop 3) Nested Loop For and while loop are also called as entry- controlled loops.
- 7. Questions to be Asked ?? In the exam questions can be asked are 1) What do you mean by loop control statement explain in detail. Answer: Must include: syntax, example, flowchart, entry control and exit control loop difference 2) Write a program ………..
- 9. for Loop Example for index = values, statements, end executes a group of statements in a loop for a specified number of times. values has one of the following forms: initVal:endVal — Increment the index variable from initVal to endVal by 1, and repeat execution of statements until index is greater than endVal. initVal:step:endVal — Increment index by the value step on each iteration, or decrements index when step is negative. valArray — Create a column vector, index, from subsequent columns of array valArray on each iteration. For example, on the first iteration, index = valArray(:,1). The loop executes a maximum of n times, where n is the number of columns of valArray, given by numel(valArray(1,:)). The input valArray can be of any MATLAB data type, including a character vector, cell array, or struct.
