用MKL减去两个矩阵
[英]Subtracting two matrices with MKL
问题描述
I am unable to find out which function to use in MKL for subtracting two 1D matrices (ex. Y = A - B). 
我无法找出在MKL中使用哪个函数来减去两个1D矩阵（例如Y = A-B）。
I went over the documentation related to multiplying matrices ( http://software.intel.com/sites/products/documentation/doclib/mkl_sa/11/tutorials/mkl_mmx_c/GUID-36BFBCE9-EB0A-43B0-ADAF-2B65275726EA.htm ) but there doesn't seem to be any addition/subtraction examples out there. 我查看了与乘法矩阵相关的文档（ http://software.intel.com/sites/products/documentation/doclib/mkl_sa/11/tutorials/mkl_mmx_c/GUID-36BFBCE9-EB0A-43B0-ADAF-2B65275726EA.htm ）但似乎没有任何加法/减法的例子。

对于密集矩阵，您总是将矩阵分配为长度为n*m的向量，因此您使用相应的BLAS 1级例程，例如： SAXPY(N,SA,SX,INCX,SY,INCY) <==> y = alpha*x+y
