使用更改输入值从Matlab运行C ++的.exe文件

Question

I have a.exe file that I got from compiling C++ code in Microsoft Visual Studio 2010. I tried to run the a.exe file from Matlab, but I put this file to work in loop with another .m file written in Matlab.

The idea is to run the .m file in Matlab inside a for loop . First, the Matlab file works with the first value of the loop and after that runs a.exe file inside Matlab with the same value and so on. I used sprintf to generate string of input for .exe file as explained below:

wvl=0.4,

for ii=1:100 wvl=0.4+i*0.01;

There are another part of Matlab code to do some calculations and prepare input data file for the C++ code:

str=sprinf('a.exe,%f',wvl);

system (str);

I am already using the command line arguments in C++ code to run the executable file with different values:

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

wvl=atof ( argv[1]);
cout << "wvl=" << wvl << endl;

The value wvl mentioned above I would like to change after compiling the code.

I don't know if the error is in the C++ code or in the Matlab code, because I got the wrong results.

Answer 1

Build it as a Matlab EXecutable (MEX) file. It can take input arguments like a Matlab function.

Your question is a little bit ambiguous: You tried to run the a.exe, but put this file to work?
