LinkLaunch

Usage

LinkLaunch["prog"]启动外部程序prog且打开一个到它的一个连接。


Notes

LinkLaunch["prog"] 运行prog作为你当前Mathematica任务的辅助进程或子进程。 • 可以使用如同 LinkLaunch["math -mathlink"]的命令从你的Mathematica任务去启动一个辅助内核进程。 • 在大多数计算机系统,用相同的参数调用LinkLaunch["prog"] 几次将启动几个prog运行进程。 • 在一些计算机系统,LinkLaunch[ ] 将进行一个程序浏览。
LinkLaunch 返回一个 LinkObject.
• 选项LinkProtocol指定使用的隐含数据传输协议。
LinkLaunch 内部调用相似于MathLink库中函数MLOpenArgv() 的一个函数。
• 参见 Mathematica 全书: 2.12.7.
• 同时参见: Install, LinkCreate, LinkConnect, LinkClose.
Further Examples

LinkLaunch launches and connects to a program that is aware of MathLink. Here we launch a copy of Mathematica; a reason for doing this would be for two or more kernels to cooperate in solving a problem. This command works on any platform except the Macintosh.

In[1]:=  

Out[1]=

On the Macintosh you need to make a duplicate of MathKernel because you cannot launch an application from a single file more than once. Single quotes must surround the pathname if it contains spaces. This would be the command on the Macintosh: link = LinkLaunch["'MathKernel copy'"]

MathLink communicates using packets. When the second kernel starts up, it sends a packet containing the first input prompt to the program that launched it.

In[2]:=  

Out[2]=

To send an expression to the second kernel for evaluation, wrap it in an EvaluatePacket; the result comes back in a ReturnPacket. The Unevaluated around the expression keeps it from evaluating before it is sent.

In[3]:=  

Out[3]=

When you are finished, quit the second kernel.
