描述

算子 mult_matrixmult_matrixMultMatrixMultMatrixMultMatrixmult_matrix computes the product of the input matrices MatrixA and MatrixB defined by the matrix handles MatrixAIDMatrixAIDMatrixAIDMatrixAIDmatrixAIDmatrix_aid and MatrixBIDMatrixBIDMatrixBIDMatrixBIDmatrixBIDmatrix_bid. A new matrix MatrixMult is generated with the result. The operator returns the matrix handle MatrixMultIDMatrixMultIDMatrixMultIDMatrixMultIDmatrixMultIDmatrix_mult_id of the matrix MatrixMult.可通过算子 get_full_matrixget_full_matrixGetFullMatrixGetFullMatrixGetFullMatrixget_full_matrix 等方式访问该矩阵的元素。If desired, one or both input matrices will be transposed for the multiplication.

The type of multiplication can be selected via MultTypeMultTypeMultTypeMultTypemultTypemult_type:

'AB'"AB""AB""AB""AB""AB"：

The matrices MatrixA and MatrixB will not be transposed. Therefore, 结果的计算公式为：

The number of columns of the matrix MatrixA must be identical to the number of rows of the matrix MatrixB.

示例：

'ATB'"ATB""ATB""ATB""ATB""ATB"：

The matrix MatrixA will be transposed. The matrix MatrixB will not be transposed. Therefore, 结果的计算公式为：

The number of rows of the matrix MatrixA must be identical to the number of rows of the matrix MatrixB.

示例：

'ABT'"ABT""ABT""ABT""ABT""ABT"：

The matrix MatrixA will not be transposed. The matrix MatrixB will be transposed. Therefore, 结果的计算公式为：

The number of columns of the matrix MatrixA must be identical to the number of columns of the matrix MatrixB.

示例：

'ATBT'"ATBT""ATBT""ATBT""ATBT""ATBT"：

The matrix MatrixA and the matrix MatrixB will be transposed. Therefore, 结果的计算公式为：

The number of rows of the matrix MatrixA must be identical to the number of columns of the matrix MatrixB.

示例：

执行信息

• 多线程类型：可重入（与非独占算子并行运行）。
• 多线程作用域：全局（可从任何线程调用）。
• 未采用并行化处理。
