MKL库中基本线性代数子程序,BLAS(Basic Linear Algebra Subprograms)库,是一个API标淮,用以规范发布基础线性代数操作的数值库(如向量或矩阵乘法)。其中CBLAS是BLAS的C语言接口。 库中前缀用来区分所支持处理的数据类型。 | 前缀 | 描述 | 函数名系列

__tmp_xdgemm.c:(.text+0xb27): undefined reference to `mkl_blas_dgemv'I am using the example code that came with the MKL. The function call that leads to this error is 'cblas_dgemm'I am compiling using the following command:icc -o MatrixMul_MKL cblas_dgemmx....
If i understand correctly, yes, cblas_dgemm perform matrix -matrix multiplication, that equal matrix-vector multiplication with multiply vectors at once. for example, for (i loop) Ci = A*Bi for (i = 0; i < N; i++) { cblas_dgemv(CblasRowMajor,CblasNoTrans,N,N,alpha,a,N,&b,N,bet...
