一定是要C语言，C++也可。

读取命令行参数(命令行参数是一个程序文件名)

执行命令行参数对应的程序

监视这个程序，直到运行的程序结束后 ，本程序才退出

最佳答案

Linux 下：

int main(int argc, char *argv[])

{

int child_reply_value;

char command[40];

if(argc != 2)

{

printf("[当前程序] [需执行的文件路径]\n");

return -1;

}

sprintf(command, "%sargv[]", "./"); //为另一个程序添加执行命令

if(0 == fork()) //创建子进程

{

execlp( command, NULL ); //替换为另一个程序

}

else

{

wait(&child_reply_value); //等待子进程结束

printf( " child process return %d\n", rtn );

}

return 0;

}

你有没有先mex -setup? 先这样然后再mbuild -setup

我做了一下，给你参考：

>> mex -setup

please choose your compiler for building external interface (mex) files:

would you like mex to locate installed compilers [y]/n? n

select a compiler:

[1] intel c++ 9.1 (with microsoft visual c++ 2005 sp1 linker)

[2] intel visual fortran 10.1 (with microsoft visual c++ 2005 sp1 linker)

[3] intel visual fortran 9.1 (with microsoft visual c++ 2005 sp1 linker)

[4] lcc-win32 c 2.4.1

[5] microsoft visual c++ 6.0

[6] microsoft visual c++ .net 2003

[7] microsoft visual c++ 2005 sp1

[8] microsoft visual c++ 2008 express

[9] microsoft visual c++ 2008 sp1

[10] open watcom c++

[0] none

compiler: 9

your machine has a microsoft visual c++ 2008 sp1 compiler located at

e:\microsoft visual studio 9.0. do you want to use this compiler [y]/n? y

please verify your choices:

compiler: microsoft visual c++ 2008 sp1

location: e:\microsoft visual studio 9.0

are these correct [y]/n? y

***************************************************************************

warning: mex-files generated using microsoft visual c++ 2008 require

that microsoft visual studio 2008 run-time libraries be

available on the computer they are run on.

if you plan to redistribute your mex-files to other matlab

users, be sure that they have the run-time libraries.

***************************************************************************

from template: e:\softct~1\matlab~2\bin\win32\mexopts\msvc90opts.bat

done . . .

>> mbuild -setup

please choose your compiler for building standalone matlab applications:

would you like mbuild to locate installed compilers [y]/n? n

select a compiler:

[1] lcc-win32 c 2.4.1

[2] microsoft visual c++ 6.0

[3] microsoft visual c++ .net 2003

[4] microsoft visual c++ 2005 sp1

[5] microsoft visual c++ 2008 express

[6] microsoft visual c++ 2008 sp1

[0] none

compiler: 2

the default location for microsoft visual c++ compilers is c:\program files\microsoft visual studio,

but that directory does not exist on this machine.

use c:\program files\microsoft visual studio anyway [y]/n? y

please verify your choices:

compiler: microsoft visual c++ 6.0

location: c:\program files\microsoft visual studio

are these correct [y]/n? y

warning: mbuild requires that the microsoft visual c++ 6.0

directories "vc98" and "common" be located within the same parent directory.

(expected to find these directories in 'c:\program files\microsoft visual studio'.)

c:\mathworks\matlab\r2009a\compopts.bat

linux下的话。

要被执行的程序要先生成一个可执行文件。

然后用system

如system("./(可执行文件的名字)");

这个可执行文件应该跟程序在同一个目录下。
