Summary
NDARRAY is a data type, which is designed to transfer N-dimensional numerical array.
Message Types
NDARRAY
| Data | Type | Description |
| TYPE | UINT8 | Scalar type (2:int8 3:uint8 4:int16 5:uint16 6:int32 7:uint32 10:float32 11:float64 13:complex float 64*) |
| DIM | UINT8 | Dimension of array |
| SIZE | UINT16[DIM] | Size of array |
| DATA | TYPE[SIZE[0]][SIZE[1]]....[[SIZE[DIM-1]]] | Array data. (Must be in network byte order.) |
2/16/2011: Complex number support is added.
- Complex is a 128-bit variable consisting of a real part in the first 64-bit and an imaginal part in the last 64-bit.
Memory layout of DATA field
Like multi-dimensional array in C/C++, DATA field is laid out in sequentially in a byte stream. For example, if the value of DATA is defined by:
char data[3][3] = {{1, 2, 3},
{4, 5, 6},
{7, 8, 9}
};
the layout in the byte stream can be visualized as follows:
+-+-+-+-+-+-+-+-+-+ |1|2|3|4|5|6|7|8|9| +-+-+-+-+-+-+-+-+-+
GET_NDARRAY
| Data | Type | Description |
STT_NDARRAY
N/A
STP_NDARRAY
N/A
RTS_NDARRAY
N / A
Implementations
The NDARRAY message type is implemented in the following source code.
