Running a script file inside c++ code

[sumeet kumar]

Hello all,

I am using octave parser to evaluate _expression_ inside my c++ code. The expressions can be very simple can can also be complicated  depending upon the user.

1)So basically, I have a string which contains all the commands that needs to be executed by octave. But I am unable to execute and get the results of the string containing commands.

2)So, I found another way, in which I write the string in an file and then parse it using octave as

    char *oct_argv[3] = {(char*)"embeded",(char*)"-q",(char*)"--interactive"};
    octave_main(3,oct_argv,true);
    ofstream ScriptFile("script", ios::out);
    ScriptFile << function ;
    ScriptFile.close();
    source_file("script");

where function is the string that needs to be evaluated.

The second approach works but the problem is very slow because of generation of file each time I want a computation. I usually end up in thousands/millions of them and it gets extremely slow, like taking days.. to complete.

In order to be more efficient, i want to do it as 1st way. So anybody has any idea, how to do it more faster/effecient or how to do as in first way.
