Creates a primitive descriptor for a matrix multiplication primitive.
Parameters:
primitive_desc |
Output primitive descriptor. |
engine |
Engine to use. |
src_desc |
Source memory descriptor (matrix A) |
weights_desc |
Weights memory descriptor (matrix B) |
bias_desc |
Bias memory descriptor. Passing NULL, a zero memory descriptor, or a memory descriptor with format_kind set to dnnl_format_kind_undef disables the bias term. |
dst_desc |
Destination memory descriptor (matrix C). |
attr |
Primitive attributes (can be NULL). |
Returns:
dnnl_success on success and a status describing the error otherwise.
