matlab.indexing.isScalarClass

Determine whether input is scalar class

Since R2024b

Syntax

TF = matlab.mixin.isScalarClass(A)

Description

TF = matlab.mixin.isScalarClass(A) returns logical 1 (true) if A is a function handle or an instance of a class that inherits from matlab.mixin.Scalar. Otherwise, it returns logical 0 (false).

Verify That Function Handle Is Scalar

Define a function handle f.

f = @sin;

Function handles are scalar by default. Verify that f is a scalar.

matlab.indexing.isScalarClass(f)

ans =

  logical

   1

Input Arguments

`A` — Input array
array

The function accepts arrays of any size, but it returns false if the input is not scalar. For example, the function returns false for a cell array of function handles, even though the function handles themselves are scalar.
