parfor 还没有真正在八度音阶中实现.关键字被接受，但只是 for 的同义词 (http://Octave.1599824.n4.nabble.com/Parfor-td4630575.html).

parfor is not really implemented in octave yet. The keyword is accepted, but is a mere synonym of for (http://octave.1599824.n4.nabble.com/Parfor-td4630575.html).

并行包的pararrayfun 和parcellfun 函数在多核机器上很方便.它们通常可以很好地替代 parfor 循环.

The pararrayfun and parcellfun functions of the parallel package are handy on multicore machines. They are often a good replacement to a parfor loop.

示例见http://wiki.octave.org/Parallel_package.要安装，请发出(仅一次)

For examples, see http://wiki.octave.org/Parallel_package. To install, issue (just once)

pkg install -forge parallel

然后，每个会话一次

pkg load parallel
