Now let’s go back up and change this input grade to something less than 60.

So I click run and we get pass and that is what I would expect because my grade was greater than or equal to 60. So let’s run the program and see what we get here output to the command window. In this case I will choose let’s say 70 then I will add a semicolon on the end of this line to suppress the output and next we will move to implementing our if statement, so we say if our grade is greater than or equal to 60 this is our logical expression and the greater than or equal to is our relational operator. So in the grade variable we are going to assign it a value and you can assign it anything that you would like. So we are start off our program by entering a numeric grade and we are going to store it in a variable called grade because that just makes sense. So let’s go over to MATLAB now and implement this. In this example 65 and if this grade is greater than or equal to 60, if that is true we will know we have passed the class and the program will end. So here is a flowchart of the example that we are going to work in MATLAB and in this case what we are trying to do is take an input grade. However if this logical expression is false the program will just end. Such as less than, greater than or equal to and if this logical expression evaluates is true then the program will execute one or more statements and then end. This logical expression is going to consist of one or more of these relational operators. So, we start the program with some sort of input and we evaluate this input using a logical expression. In a flowchart of the if statement as given below, flowcharts are super useful for documenting the paths that a program can take. Let’s get started.īefore we jump into MATLAB Programming, let’s take a look at the structure of the if statement.

Here we discuss the various examples of the if-else statements in Matlab along with different conditions and code implementation.Conditional Statements in Matlab- In this tutorial, we will introduce you to the conditional statements if, if-else, and else if and then I will show you through examples, how to implement each of these statements in MATLAB. This is a guide to IF-Else Statement in Matlab. If ( a >= min ) & & ( a = min ) & & ( a ’ ( greater than), ‘ = ’ (greater than equal l to), ‘ < = ’ ( less than equal to), ‘ & ’ ( logical and ), ‘ =! ’( not equal to), ‘ || ’ ( logical or ), etc. If ( a c ) - nested if condition 4ĭisp ( ' b is max ' ) if condition 4 is true if condition 2 is trueĭisp ( ' c is maximum ' ) -if condition 2 is false In this example, we will see a maximum of three numbers, let us consider three numbers a, b and c. Screen 2: Matlab implementation of example 2 Example #3 – Use of Nested if Statement Screen 2 shows the Matlab implementation of example 2. Let us take two number ‘ a ’ and ‘ b ’.ĭisp ( ' a is maximum ' ) - condition 1 is trueĭisp (' b is minimum ' ) -condition 1 is false Screen 1: Matlab implementation of example 1 Example #2 – Comparison of Two NumbersĬonsider the second example to find out the maximum of two numbers. Screen 1 shows the Matlab implementation of example 1.
