mustBeLessThanOrEqual

Validate that value is less than or equal to another value or issue error

Syntax

mustBeLessThanOrEqual(A,B)

Description

example

mustBeLessThanOrEqual(A,B) issues an error if all elements in A are not less than or equal to the scalar B. This function does not return a value.

mustBeLessThanOrEqual accepts user-defined objects if the class of the object implements these methods:

Examples

collapse all

Use mustBeLessThanOrEqual to validate that the values in the first input are less than or equal to the value of the second input.

mustBeLessThanOrEqual([3 4 5],2)
Error using mustBeLessThanOrEqual (line 18)
Values must be less than or equal to 2.

Constrain property values to be less than or equal to a specified value.

This class constrains the value of Prop1 to be less than or equal to 2.

classdef MyClass
   properties
      Prop1 {mustBeLessThanOrEqual(Prop1,2)}
   end
end

Create an object and assign a value to its property.

obj = MyClass;
obj.Prop1 = 3;
Error setting 'Prop1' property of 'MyClass' class:
Values must be less than or equal to 2.

When you assign a value to the property, MATLAB® calls mustBeLessThanOrEqual with the value being assigned to the property. mustBeLessThanOrEqual issues an error because the value 3 is not less than or equal to 2.

Input Arguments

Value to validate, specified as a scalar or an array of one of the following:

Value that A must be less than or equal to, specified as a scalar of one of the following:
