Arguments to TRMM:
|
||
|
|
||
|
* `const Layout`: Data-layout of the matrices, either `Layout::kRowMajor` (101) for row-major layout or `Layout::kColMajor` (102) for column-major data-layout.
|
||
|
* `const Side`: The horizontal position of the triangular matrix, either `Side::kLeft` (141) or `Side::kRight` (142).
|
||
|
* `const Triangle`: The vertical position of the triangular matrix, either `Triangle::kUpper` (121) or `Triangle::kLower` (122).
|
||
|
* `const Transpose`: Transposing the input matrix A, either `Transpose::kNo` (111), `Transpose::kYes` (112), or `Transpose::kConjugate` (113) for a complex-conjugate transpose.
|
||
|
* `const Diagonal`: The property of the diagonal matrix, either `Diagonal::kNonUnit` (131) for a non-unit values on the diagonal or `Diagonal::kUnit` (132) for a unit values on the diagonal.
|
||
|
* `const size_t m`: Integer size argument.
|
||
|
* `const size_t n`: Integer size argument.
|
||
|
* `const T alpha`: Input scalar constant.
|
||
|
* `const cl_mem a_buffer`: OpenCL buffer to store the input A matrix.
|
||
|
* `const size_t a_offset`: The offset in elements from the start of the input A matrix.
|
||
|
* `const size_t a_ld`: Leading dimension of the input A matrix.
|
||
|
* `cl_mem b_buffer`: OpenCL buffer to store the output B matrix.
|
||
|
* `const size_t b_offset`: The offset in elements from the start of the output B matrix.
|
||
|
* `const size_t b_ld`: Leading dimension of the output B matrix.
|
||
|
* `cl_command_queue* queue`: Pointer to an OpenCL command queue associated with a context and device to execute the routine on.
|
||
|
* `cl_event* event`: Pointer to an OpenCL event to be able to wait for completion of the routine's OpenCL kernel(s). This is an optional argument.
