DXNewArray, DXNewArrayV

Function

Create an irregular Array Object.

Syntax


#include <dx/dx.h>
Array DXNewArray(Type t, Category c, int rank, ...)
Array DXNewArrayV(Type t, Category c, int rank, int *shape)

Functional Details

The Object created is an Array of Array subclass CLASS_ARRAY. Each item is a scalar, vector, matrix, or tensor whose rank is specified by rank (number of dimensions).

The first form of this routine (DXNewArray) specifies the shape as the last rank arguments. The second form (DXNewArrayV) specifies shape as an Array of integers. Each entry in the item is real or complex, as specified by c, with coefficients that are integer, single precision, and double precision, according to t. The Array initially contains no items.

The type is one of the following:


TYPE_BYTE            TYPE_HYPER        TYPE_SHORT
TYPE_UBYTE           TYPE_INT          TYPE_USHORT
TYPE_DOUBLE          TYPE_UINT         TYPE_STRING
TYPE_FLOAT

The category is CATEGORY_REAL or CATEGORY_COMPLEX.

Return Value

Return the Array or return NULL and set an error code.

DXAddArrayData
