![]() ![]() Here is an example showing if, else, and elseif. 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 input argument func is a function handle to a function that takes one input argument and returns a scalar. Function handles can represent either named or anonymous. ![]() ![]() For example, you can use function handles as input arguments to functions that evaluate mathematical expressions over a range of values. A typical use of function handles is to pass a function to another function. 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)). A function handle is a MATLAB ® data type that represents a function. The latter is used in a linear sequence of conditional statements with only one terminating end. B arrayfun (func,A) applies the function func to the elements of A, one element at a time. The former introduces a new, nested if, which must have a matching end. The workaround is similar to what Adam has mentioned, is that you can create a regular function and pass the function handle in. 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. First of all, you cannot add a complex if statement in an anonymous function. If now we really want the value (2x)2, we could try to write it the way that you wrote your statement in your question. 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. So for example, if we had a function handle: func (x)2x If we evaluation this, by calling it with an input value for x. Elseif (MATLAB Functions) MATLAB Function Reference I'm trying to define an anonymous function using an 'if' statement. ![]()
