cblas_sgemm()为openBLAS库实现矩阵乘法的函数。直接上例子代码: floata[3]={2,3,4};floatb[3]={1,0,1};floatc[1]={0};cblas_sgemm(CblasRowMajor,CblasNoTrans,CblasTrans,1,1,3,1.0,a,3,b,3,0.0,c,1);cout<<c[0]<<endl; CblasRowMajor:矩阵的读取方式之一,表示行主序。若a[6]={1,2,...
cblas_sgemm(CblasRowMajor, CblasNoTrans, CblasNoTrans, M, N, K, 0.0f, U, K, V, N, 1.0f, M, N); 单核情况下,其于部分代码不变,只修改贝塔参数,设置为0.0f时性能为11Gflops.设置为1.0f时性能为40Gflops。这两个都通过了正确性校验,硬件为鲲鹏920.我找不到问题的原因,各位大佬有什么办法吗暂无...

Hi Xianyi, We tried to run a matrix multiplication with cblas_sgemm or cblas_dgemm on android. We tried with A = [1 3 4 6], B = [3 5 9 1], and C = A * B. We initialized C with all zero. The result of C did not end up with A * B, but rema...
确认cblas_sgemm函数的来源库: cblas_sgemm函数是CBLAS库的一部分,CBLAS是BLAS(Basic Linear Algebra Subprograms)的一个C语言接口。它用于执行单精度浮点数矩阵乘法。因此,你需要确保你的项目中包含了CBLAS库。 检查是否已经正确安装并链接了该库: 确保CBLAS库已经正确安装在你的系统上。如果你使用的是Linux系统,可以...
