MatMul

Scenario Description

Execute two input tensors a and b and the parameter structure M, perform multiplication operations on two matrices, and store the calculation results in the output tensor. For example:

a: [1,2,
    3,4]
b: [5,6,
    7,8]
output: [19,22,
         43,50]

Code Example

#include <cmath>
#include <random>
#include <cstdint>
#include <iostream>

#include "ktfop.h"
int main()

    params.order = CblasRowMajor;     // Matrix storage order (row-major or column-major order).
    params.transA = CblasNoTrans;     // Matrix A is transposed or not.
    params.transB = CblasNoTrans;     // Matrix B is transposed or not.
    params.m = 2;                     // Number of rows in matrix A.
    params.n = 2;                     // Number of columns in matrix B.
    params.k = 2;                     // Number of columns in matrix A or number of rows in matrix B.
    params.alpha = 1.0f;              // alpha parameter.
    params.lda = 2;                   // Storage stride of matrix A.
    params.ldb = 2;                   // Storage stride of matrix B.
    params.beta = 0.0f;               // beta parameter.
    params.ldc = 2;                   // Storage stride of matrix C.
    float a[4] = {1, 2, 3, 4};        // Initialize the matrices involved in the calculation.
    float b[4] = {5, 6, 7, 8};
    float c[4] = {0, 0, 0, 0};        // Matrix that stores the calculation results.
    int ret = -1;
    ret = Matmul(a, b, c, params);   // Call the Matmul operator and store the results in the c array.
    std::cout << "c: [";
