Signature

Description

The operator create_dl_layer_matmulcreate_dl_layer_matmulCreateDlLayerMatmulCreateDlLayerMatmulcreate_dl_layer_matmul creates a MatMul layer whose handle is returned in DLLayerMatMulDLLayerMatMulDLLayerMatMulDLLayerMatMuldllayer_mat_mul.

A MatMul layer multiplies the 2D matrices, given in the latter two dimensions (H, W) of input DLLayerADLLayerADLLayerADLLayerAdllayer_a, with the corresponding 2D matrices of input DLLayerBDLLayerBDLLayerBDLLayerBdllayer_b, also given in the latter two dimensions (H, W). The output in DLLayerMatMulDLLayerMatMulDLLayerMatMulDLLayerMatMuldllayer_mat_mul is hence given by .

The MatMul layer supports broadcasting for the first input DLLayerADLLayerADLLayerADLLayerAdllayer_a. That means, if the batch size or the number of channels in DLLayerADLLayerADLLayerADLLayerAdllayer_a equals one then the first batch item or channel of DLLayerADLLayerADLLayerADLLayerAdllayer_a is multiplied with all batch items or channels of DLLayerBDLLayerBDLLayerBDLLayerBdllayer_b, respectively.

To make the multiplication work, the width of DLLayerADLLayerADLLayerADLLayerAdllayer_a must be equal to the height of DLLayerBDLLayerBDLLayerBDLLayerBdllayer_b.

The following generic parameters GenParamNameGenParamNameGenParamNamegenParamNamegen_param_name and the corresponding values GenParamValueGenParamValueGenParamValuegenParamValuegen_param_value are supported:

'is_inference_output'"is_inference_output""is_inference_output""is_inference_output""is_inference_output":
