可惜mingw4.6到现在还没出来。
gcc4.6的 for 新特性在windows下不能体验了, 恨不得自己编译一个mingw

windows下为什么不用vs 或Intel c++ ?

看了一下,gsl-1.15 的cblas_dgemm函数,双精度浮点矩阵乘法,接口符合cblas规范。
采用的是三重循环:/* formC := alpha*A*B + C */

    for (k = 0; k < K; k++) {
      for (i = 0; i < n1; i++) {
      const BASE temp = alpha * F;
      if (temp != 0.0) {
          for (j = 0; j < n2; j++) {
            C += temp * G;
          }
      }
      }
    }

MinGW distribution ("distro") currently contains GCC 4.6.1 and Boost 1.47.0.
mingw-7.2.exe (16.8 MB) : This is a self-extracting archive. It's incredibly easy to install; see How To Install below.
解压就可以了。
