Here we discuss the Working of if Statement in Matlab with Examples. Answers (2) Do more vectorized processing. This has been a guide to If Statement in Matlab. Use if, elseif, and else for Conditional Assignment. An if block can include multiple elseif blocks. We can also use nested if statements in the programs depending on the business requirements. The statements execute only if previous expressions in the if.end block are false. Relational operators like, =, = and logical operators like ||, & can be used in the expression of if statement. If statement is used to compare the conditions of arrays and character vector as well. After checking, the result is false so it will check the second condition in elseif line and since it is true, it will display the output as “Hello2” ignoring the else part. In the first line of the code, since & operator is used, it checks if both the conditions are met and then only it will execute the consecutive statement. Here if statement is used to check multiple conditions.
#Else if matlab code#
Here the output of the above code is Y= 7 if we print it since 0.921 and 0.990 are greater than 0.9. A true expression has either a logical true or nonzero value. If not then, it will give the statement as given in the else part. elseif (MATLAB Functions) elseif Conditionally execute statements Syntax if expression1 statements1 elseif expression2 statements2 end Description If expression1 evaluates as false and expression2 as true, MATLAB executes the one or more commands denoted here as statements2. If there are any values greater, than it will give Y = 7 if we print it. If condition checks whether any value is greater than 0.9 or the value assigned to limit. According to the input arguments in the rand function, it will generate 5 random numbers between 0 and 1. In the above example, the limit is assigned a value as 0.9 and rand function is used to generate random numbers. Please find the below examples for better understanding: Example# 5 If statement is for multiple purposes like to compare array or character vectors. Since neither of the above two expressions are true it will execute the else block and display the output as 2. The first expression is xy which is also false. For more information on those topics see one of our tutorials on vectors (Introduction to Vectors in Matlab), matrices (Introduction. In Example 4, x and y values are assigned as 5. First statement checks whether the condition is true or not, here the expression is to check whether xy which is true, so it will execute the subsequent statement and display the output as z =1. In Example 3, x and y values are assigned as 5 and 3. Matlab Else if statement: Now while this is much more desirable than just using an if statement alone what if we want to have more than one logical expression.So for example it may be more desirable to show the letter grade that we have received in the course. Please find the above two examples describing the working of elseif statement. Here is an example showing if, else, and elseif.Else if block is used between if statement and else statement. Exactly one of the four assignments to x is executed, depending upon the values of the three logical expressions, A, B, and C. The two segments shown below produce identical results. The latter is used in a linear sequence of conditional statements with only one terminating end. The former introduces a new, nested if, which must have a matching end. When nesting ifs, each if must be paired with a matching end. For nonscalar expressions, (for example, is matrix A less then matrix B), true means that every element of the resulting matrix has a logical true or nonzero value.Įxpressions usually involve relational operations such as (count = 0).Įlse if, with a space between the else and the if, differs from elseif, with no space. MATLAB evaluates the expression and, if the evaluation yields a logical true or nonzero result, executes one or more MATLAB commands denoted here as statements. language fundamentals Loops and Conditional Statements MATLAB. If expression1 evaluates as false and expression2 as true, MATLAB executes the one or more commands denoted here as statements2.Ī true expression has either a logical true or nonzero value. Matlab function: if, elseif, else Execute statements if condition is true. Control passes to the statement following the end of that loop. and an else statement, which is very useful to test various conditions. In nested loops, break exits only from the loop in which it occurs. MATLAB - if. Statements, An if statement can be followed by one (or more) optional elseif. Statements in the loop that appear after the break statement are not executed. Elseif (MATLAB Functions) MATLAB Function Reference The break statement terminates execution of for or while loop.
