modified givens rotation for double elements

Parameters

[in]	N	Number of elements in vector X and Y.
[out]	X	Buffer object storing vector X.
[in]	offx	Offset of first element of vector X in buffer object. Counted in elements.
[in]	incx	Increment for the elements of X. Must not be zero.
[out]	Y	Buffer object storing the vector Y.
[in]	offy	Offset of first element of vector Y in buffer object. Counted in elements.
[in]	incy	Increment for the elements of Y. Must not be zero.
[in]	DPARAM	Buffer object that contains SPARAM array of minimum length 5 DPARAM(1)=DFLAG DPARAM(2)=DH11 DPARAM(3)=DH21 DPARAM(4)=DH12 DPARAM(5)=DH22
[in]	offDparam	Offset of first element of array DPARAM in buffer object. Counted in elements.
[in]	numCommandQueues	Number of OpenCL command queues in which the task is to be performed.
[in]	commandQueues	OpenCL command queues.
[in]	numEventsInWaitList	Number of events in the event wait list.
[in]	eventWaitList	Event wait list.
[in]	events	Event objects per each command queue that identify a particular kernel execution instance.

Returns

• clblasSuccess on success;
• clblasInvalidDevice if a target device does not support the floating point arithmetic with double precision;
• the same error codes as the clblasSrotm() function otherwise.

Parameters

[in]	N	Number of elements in vector X and Y.
[out]	X	Buffer object storing vector X.
[in]	offx	Offset of first element of vector X in buffer object. Counted in elements.
[in]	incx	Increment for the elements of X. Must not be zero.
[out]	Y	Buffer object storing the vector Y.
[in]	offy	Offset of first element of vector Y in buffer object. Counted in elements.
[in]	incy	Increment for the elements of Y. Must not be zero.
[in]	SPARAM	Buffer object that contains SPARAM array of minimum length 5 SPARAM(1)=SFLAG SPARAM(2)=SH11 SPARAM(3)=SH21 SPARAM(4)=SH12 SPARAM(5)=SH22
[in]	offSparam	Offset of first element of array SPARAM in buffer object. Counted in elements.
[in]	numCommandQueues	Number of OpenCL command queues in which the task is to be performed.
[in]	commandQueues	OpenCL command queues.
[in]	numEventsInWaitList	Number of events in the event wait list.
[in]	eventWaitList	Event wait list.
[in]	events	Event objects per each command queue that identify a particular kernel execution instance.

Returns

• clblasSuccess on success;
• clblasNotInitialized if clblasSetup() was not called;
• clblasInvalidValue if invalid parameters are passed:
  • N is zero, or
  • either incx or incy is zero, or
  • the vector sizes along with the increments lead to accessing outside of any of the buffers;
• clblasInvalidMemObject if either X, Y or SPARAM object is Invalid, or an image object rather than the buffer one;
• clblasOutOfHostMemory if the library can't allocate memory for internal structures;
• clblasInvalidCommandQueue if the passed command queue is invalid;
• clblasInvalidContext if a context a passed command queue belongs to was released;
• clblasInvalidOperation if kernel compilation relating to a previous call has not completed for any of the target devices;
• clblasCompilerNotAvailable if a compiler is not available;
• clblasBuildProgramFailure if there is a failure to build a program executable.
