SetTraverse

Function Usage

Sets the traversal mode, that is, M axis first or N axis first.

Prototype

int32_t SetTraverse(MatrixTraverse traverse)

Parameters

Table 1 Parameters

Parameter

Input/Output

Description

traverse

Input

Fixed Matmul computation direction. Possible values are MatrixTraverse::FIRSTM and MatrixTraverse::FIRSTN.

FIRSTM indicates that offsetting is performed along the M-axis direction first and then along the N-axis direction.

FIRSTN indicates that offsetting is performed along the N-axis direction first and then along the M-axis direction.

Returns

-1: setting failed; 0: setting succeeded.

Precautions

None
