Matlab arguments validation syntax is generally recommended over the legacy validateattributes. The arguments specification coerces the data to fix the class declaration given if possible, and errors otherwise.

• Default values are easily specified, which required such verbose syntax before.
• only a single class can be specified
• recall the .empty method of most Matlab classes e.g. datetime.empty() that allows initializing an empty array.

Note: the Matlab argument validation syntax coerces class at runtime.
