"NumericArray" (Compiled Type)


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


  • "NumericArray" can be used in Typed and related constructs to specify a type.


  • NumericArray[{},type] creates a numeric array with the specified element type.
  • CreateTypeInstance["NumericArray"::[type,rank],array] constructs a copy of array.
  • CreateTypeInstance["NumericArray"::[type,1],carr,len] constructs a numeric array from a "CArray" carr with length len. carr can optionally be wrapped in "Managed".


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



  • "NumericArray" objects can be converted to and from NumericArray expressions.
  • "ListVector"

  • "NumericArray" objects can be converted to and from "ListVector" objects.

Runtime Errors


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

Basic Examples  (2)

"NumericArray" can be used as an input and output from a CompiledCodeFunction.

Compile a function that returns a "NumericArray":

Use Normal to convert the "NumericArray" to a list:

Possible Issues  (1)

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:
