    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).

    example

    Examples

    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

    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.
