"PackedArray"::[type,rank]

represents a packed array composite type with elements of specified type and rank.

• "PackedArray" can be used in Typed and related constructs to specify a type.
• "PackedArray" objects are automatically memory managed.
• Only elements that have a type of "MachineInteger", "Real64" or "ComplexReal64" can be stored in a "PackedArray".

• Packed arrays can be created with List in compiled code. »
• CreateTypeInstance["PackedArray"::[type,rank],array] constructs a copy of array.
• CreateTypeInstance["PackedArray"::[type,1],carr,len] constructs a packed array from a "CArray" carr with length len. carr can optionally be wrapped in "Managed".

• Information[array,"ElementType"] for array of type "PackedArray"::[type,rank] gives type .

Expressions
• "PackedArray" objects can be converted to and from List objects of the appropriate form. For a List object to be converted to an object of type "PackedArray"::[type,rank], it must represent a rectangular array with the specified rank and element type.
"ListVector"
• "PackedArray" objects can be converted to and from "ListVector" objects.

ArrayPartError
• Elements with types constructed from "PackedArray" can give a runtime error if used in an operation that extracts or sets parts.

"PackedArray" can be used as an input and output from a CompiledCodeFunction:

Create a packed array in compiled code:

"MachineInteger" is useful for working with "PackedArray", since this takes integers of the native size for the architecture:

Part access can cause an error while running the function. The computation is terminated, a message is issued and the Wolfram Engine is used to compute the result:
