Size information for property validation

Renamed from meta.ArrayDimension in R2024a

Description

matlab.metadata.ArrayDimension is an abstract class used to define subclasses that represent the size information defined by property validation. These subclasses enable a complete description of property size information:

• matlab.metadata.FixedDimension - Dimension specified as a fixed numeric value
• matlab.metadata.UnrestrictedDimension - Dimension specified as a colon, which indicates any value is allowed

Version History

Introduced in R2018a

The namespace of ArrayDimension has been changed frommeta to matlab.metadata. The behavior remains the same.

MATLAB® will continue to recognize the old metaclass names in most contexts. However, code that relies on string comparisons to identify metaclasses might need to be updated to continue to work as expected. For example, if mObj in the example below is a matlab.metadata.ArrayDimension instance, the code under the case statement for'meta.ArrayDimension' does not execute becauseclass(mObj) returns'matlab.metadata.ArrayDimension'.

switch class(mObj) case 'meta.ArrayDimension' % code to execute if mObj is a % meta.ArrayDimension instance ... end

To ensure this code continues to work as intended, use an if statement with isa. The isa command recognizes both the old and new names of the class.

if isa(mObj,'meta.ArrayDimension') % code to execute if mObj is a % matlab.metadata.ArrayDimension instance else ... end

If compatibility with older releases of MATLAB is not a concern, you can update'meta.ArrayDimension' to'matlab.metadata.ArrayDimension'. However, continue to use the old name if your code needs to run on versions of MATLAB before R2024a.
