Property Class and Size

MATLAB applies any class and size validation defined for a property before calling

validation functions. Assignment to a property that defines size or class validation is

analogous to assignment to a MATLAB object array. MATLAB can apply class and size

conversions to the right side of the assignment to satisfy class and size validation.

For more information, see “Order of Validation” on page 8-27 and “Property Validation

Functions” on page 8-40.

Property Size Validation

Specify the property size as the row, column, and additional dimension following the

property name. Size validation does not support scientific notation.

classdef MyClass

properties

Prop(dim1,dim2,...) = defaultValue

end

end

Assignment and Size Validation

This class defines the size of the Location property as 1-by-3. Any value assigned to this

property must conform to that size or must be convertible to that size.

classdef ValidateProps

properties

Location(1,3)

end

end
