Input Parameters
Name |
Type |
Description |
---|---|---|
n |
const MKL_INT |
Size of the array dbuf |
dbuf |
const double |
Array of n double precision floating-point random numbers with uniform distribution over interval (a,b) |
a |
const double |
Left boundary a |
b |
const double |
Right boundary b |
dcallback |

Pointer to the callback function used for update of the array dbuf |
Output Parameters
Name |
Type |
Description |
---|---|---|
stream |
VSLStreamStatePtr* |
Descriptor of the stream state structure |
Format of the callback function:
int dUpdateFunc( VSLStreamStatePtr stream, int* n, double dbuf[], int* nmin, int* nmax, int* idx );
The callback function returns the number of elements in the array actually updated by the function.Table dcallback Callback Function Parameters gives the description of the callback function parameters.
Parameters |
Short Description |
---|---|
stream |
Abstract random stream descriptor |
n |
Size of dbuf |
dbuf |
Array of random numbers associated with the stream stream |
nmin |
Minimal quantity of numbers to update |
nmax |
Maximal quantity of numbers that can be updated |
idx |
Position in cyclic buffer dbuf to start update 0≤idx<n. |
Description
The vsldNewAbstractStream function creates a new abstract stream for double precision floating-point arrays with random numbers of the uniform distribution over interval (a,b). The function associates the stream with a double precision array dbuf and your callback function dcallback that is intended for updating of dbuf content.
Return Values
- VSL_ERROR_OK, VSL_STATUS_OK
-
Indicates no error, execution is successful.
- VSL_ERROR_BADARGS
-
Parameter n is not positive.
- VSL_ERROR_MEM_FAILURE
-
System cannot allocate memory for stream.
- VSL_ERROR_NULL_PTR
-
Either buffer or callback function parameter is a NULL pointer.
