The input argument func is a function handle to a function that takes one input argument and returns a scalar. arrayfun then concatenates the outputs from func into the output array B, so that for the i th element of A, B (i) func (A (i)). if ((attendance >= 0.90) & (grade_average >= 60))Įvery element of A is less than that same element of B with 1 added. B arrayfun (func,A) applies the function func to the elements of A, one element at a time.In this example, if both of the conditions are satisfied, then the student passes the course. It starts with the keyword if, followed by a condition, and ends with the keyword end. If the evaluated expression yields a nonscalar value, then every element of this value must be true or nonzero for the entire expression to be considered true. The Basic Syntax of an if statement in Matlab is straightforward. Statements is one or more MATLAB statements to be executed only if the expression is true or nonzero. When using elseif and/or else within an if statement, the general form of the statement isĮxpression is a MATLAB expression, usually consisting of variables or smaller expressions joined by relational operators (e.g., count = 0) That way, as your function is searching for a and T, itll still pass it through and evaluate it. When nesting ifs, each if must be paired with a matching end. ![]() 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. However, an anonymous function returns only one output. ![]() For example, this function accepts two inputs, x and y: myfunction (x,y) (x2 + y2 + xy) x 1 y 10 z myfunction (x,y) z 111. Without the parentheses, the assignment creates another function handle. Anonymous functions require that you explicitly specify the input arguments as you would for a standard function, separating multiple inputs with commas. If the function does not require any inputs, then you can call the function with empty parentheses, such as. Here is a minimum 'not working' example (my code is more convoluted, but this illustrates the issue): clc clear all. ![]() If (MATLAB Functions) MATLAB Function Reference Create a handle and call the function to compute the square of four. I'm trying to define an anonymous function using an 'if' statement.
