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. In how many ways can x = 59, 650 be written as the sum of squares of two integers m and n? In other words, find all integer pairs m, n such that m2 + n2 = x, which is equivalent to asking whether n = √x − m 2 is an integer. else if, with a space between the else and the if, differs from elseif, with no space. Execute the following M-file for a variety of different taxable incomes:Ĭlear all % file available in M-files folder as file3.mĮxample 3: Most if constructions occur inside a for or while loop. If the logical expression is true (that is, if it evaluates to logical 1), MATLAB. It also introduces MATLAB’s input command which enables data to be input from the keyboard when required by printing out a suitable message. or false, use the if statement (which may include else or elseif). Execute the following M-file for both $78.85 and then $122.40.Įxample 2: The following M-file calculates the current amount of income tax due on a given taxable income. You’ve probably also read programming books promoting the use of If-Else as the de facto branching technique. This structure allows us to execute one set of statements if a logical condition is true.
#Else if matlab code#
Suppose a shop offers a 5% discount on bills over $100. For both if and switch, MATLAB executes the code corresponding to the first true condition, and then exits the code block. You’ve watched countless tutorials using If-Else statements. Matlab provides a way to make decisions via the if-else structure. Commands evaluated if expression1 is trueĬommands evaluated if expression2 is trueĬommands evaluated if expression3 is trueĬommands evaluated if no other expression is trueĮxample 1: Let us consider a very simple situation firstly.
