MATLAB Object-Oriented Programming

Data property to specify the class as double, MATLAB converts the char vector to a

double array.

properties

Data double {mustBeNumeric, mustBeFinite}

end

The assignment to the char vector does not produce an error because MATLAB converts

the char vector to class double.

a.Data = 'cubic'

a =

ValidatorFunction with properties:

Data: [99 117 98 105 99]

Interp: 'linear'

Assignment to the Interp property requires an exact match.

a = ValidatorFunction;

a.Interp = 'cu'

Error setting property 'Interp' of class 'ValidatorFunction':

Value must be a member of this set

linear

cubic

spline

Using an enumeration class provides inexact matching and case insensitivity.

Enumeration Class for Inexact Matching

Property validation using an enumeration class provides these advantages:

• Inexact, case-insensitive matching for unambiguous char vectors or string scalars


• Conversion of inexact matches to correct values

For example, suppose that you define the InterpMethod enumeration class for the

Interp property validation.

classdef InterpMethod

enumeration

linear
