With a pool running:With no pool running:

If you set your parallel preferences to automatically create a parallel pool when necessary, you do not need to explicitly call theparpoolcommand. You might explicitly create a pool to control when you incur the overhead time of setting it up, so the pool is ready for subsequent parallel language constructs.

删除(poolobj)shuts down the parallel pool. Without a parallel pool,spmd和parforrun as a single thread in the client, unless your parallel preferences are set to automatically start a parallel pool for them.

When you use the MATLAB editor to update files on the client that are attached to a parallel pool, those updates automatically propagate to the workers in the pool. (This automatic updating does not apply to Simulink^®模型文件。要向工人传播更新的模型文件，请使用updateAttachedFilesfunction.)

If possible, the working folder on the workers is initially set to match that of the MATLAB client session. Subsequently, the following commands entered in the client Command Window also execute on all the workers in the pool:

This behavior allows you to set the working folder and the command search path on all the workers, so that subsequent pool activities such asparfor-loops execute in the proper context.

When changing folders or adding a path withcd或者addpathon clients with Windows^®operating systems, the value sent to the workers is the UNC path for the folder if possible. For clients with Linux^®operating systems, it is the absolute folder location.

If any of these commands does not work on the client, it is not executed on the workers either. For example, ifaddpath指定客户端无法访问的文件夹addpathcommand is not executed on the workers. However, if the working folder can be set on the client, but cannot be set as specified on any of the workers, you do not get an error message returned to the client Command Window.

Be careful of this slight difference in behavior in a mixed-platform environment where the client is not the same platform as the workers, where folders local to or mapped from the client are not available in the same way to the workers, or where folders are in a nonshared file system. For example, if you have a MATLAB client running on a Microsoft^®Windows操作系统在MATLAB工人都在Linux操作系统上运行时，相同的参数addpath不能同时工作。在这种情况下，您可以使用该功能pctRunOnAllto assure that a command runs on all the workers.

客户和工人之间的另一个区别是addpatharguments that are part of theMatlabrootfolder are not set on the workers. The assumption is that the MATLAB install base is already included in the workers’ paths. The rules foraddpathregarding workers in the pool are:

For example, suppose thatMatlabrooton the client isC：\ applications \ matlab \。With an open parallel pool, execute the following to set the path on the client and all workers:

addpath('P1','P2','C:\Applications\matlab\T3','C:\Applications\matlab\T4','P5','C:\Applications\matlab\T6','P7','P8'）；

BecauseT3,T4， 和T6are subfolders ofMatlabroot, they are not set on the workers’ paths. So on the workers, the pertinent part of the path resulting from this command is:

P1 P2  P5 P7 P8
