construct the modified givens rotation on double elements

Parameters

[out]	DD1	Buffer object that contains DD1
[in]	offDD1	Offset to DD1 in DD1 buffer object. Counted in elements.
[out]	DD2	Buffer object that contains DD2
[in]	offDD2	Offset to DD2 in DD2 buffer object. Counted in elements.
[out]	DX1	Buffer object that contains DX1
[in]	offDX1	Offset to DX1 in DX1 buffer object. Counted in elements.
[in]	DY1	Buffer object that contains DY1
[in]	offDY1	Offset to DY1 in DY1 buffer object. Counted in elements.
[out]	DPARAM	Buffer object that contains DPARAM array of minimum length 5 DPARAM(0) = DFLAG DPARAM(1) = DH11 DPARAM(2) = DH21 DPARAM(3) = DH12 DPARAM(4) = DH22
[in]	offDparam	Offset to DPARAM in DPARAM 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 clblasSrotmg() function otherwise.

Parameters

[out]	SD1	Buffer object that contains SD1
[in]	offSD1	Offset to SD1 in SD1 buffer object. Counted in elements.
[out]	SD2	Buffer object that contains SD2
[in]	offSD2	Offset to SD2 in SD2 buffer object. Counted in elements.
[out]	SX1	Buffer object that contains SX1
[in]	offSX1	Offset to SX1 in SX1 buffer object. Counted in elements.
[in]	SY1	Buffer object that contains SY1
[in]	offSY1	Offset to SY1 in SY1 buffer object. Counted in elements.
[out]	SPARAM	Buffer object that contains SPARAM array of minimum length 5 SPARAM(0) = SFLAG SPARAM(1) = SH11 SPARAM(2) = SH21 SPARAM(3) = SH12 SPARAM(4) = SH22
[in]	offSparam	Offset to SPARAM in SPARAM 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;
• clblasInvalidMemObject if either SX1, SY1, SD1, SD2 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.
