matlab并行一 配置matlab并行计算池

通过matlabpool命令来启动和配置Matlab并行计算池，但是在matlab2013B的帮助文档中说：

 matlabpool will be removed in a future release. Use PARPOOL instead.

所以以后应该使用parpool,先来看看帮助文档是怎么说的

parpool Create a parallel pool of workers on a cluster and return a pool object

    pool = parpool creates and returns a pool on the default cluster with its
    NumWorkers in the range [1, preferredNumWorkers] for running parallel
    language features (parfor, parfeval, parfevalOnAll, spmd, and distributed).
    preferredNumWorkers is the value defined in your parallel preferences. Use
    delete(pool) to shut down the parallel pool.
 
    pool = parpool(numWorkers) creates and returns a pool with the
    specified number of workers. numWorkers can be a positive integer or a
    range specified as a 2-element vector of integers. If numWorkers is a
    range, the resulting pool has size as large as possible in the range
