Call script shell with Qt

[faldzip]

I think this:

matlab -nojvm -nosplash -r MyCommand

matlab -nojvm -nosplash -r MyCommand

To copy to clipboard, switch view to plain text mode 

should look:

arguments << "-nojvm" << "-nosplash" << "-nodisplay" << "-r" << "addmatrix";
exec->start("matlab", arguments);

arguments << "-nojvm" << "-nosplash" << "-nodisplay" << "-r" << "addmatrix";
exec->start("matlab", arguments);

I manually launch shell and manually the start matlab in bash mode.
after start my Qt program and redirect the standartd input on the standard input of the shell as if the program wrote in shell to the place mine....CAN I DO THIS ???

As I understand, you want to pass the input from you Qt app to the matlab?
I would try starting matlab with a QProcess, and then writing and reading it's input/output, like sample code in assistant:

QProcess gzip;
gzip.start("gzip", QStringList() << "-c");
if (!gzip.waitForStarted())
	return false;
 
gzip.write("Qt rocks!");
gzip.closeWriteChannel();
 
if (!gzip.waitForFinished())
	return false;
 
QByteArray result = gzip.readAll();

QProcess gzip;
gzip.start("gzip", QStringList() << "-c");
if (!gzip.waitForStarted())
	return false;

gzip.write("Qt rocks!");
gzip.closeWriteChannel();

if (!gzip.waitForFinished())
	return false;

QByteArray result = gzip.readAll();

thanks for help ... it work... the right code is:

QStringList argo, list;
    QProcess *exec;
    exec =new QProcess(this);
    argo <<"/Applications/MATLAB_R2008a/bin/matlab"<<"-nojvm -nosplash -nodisplay -r 'addmatrix(2,7)'";
    list <<"PATH=/sw/bin:/sw/sbin:/usr/bin:/bin:/usr/sbin:/sbin:/usr/local/bin:/usr/X11/bin:/usr/X11R6/bin";
    exec->setEnvironment(list);
 
    exec->start("/bin/bash", argo);

QStringList argo, list;
    QProcess *exec;
    exec =new QProcess(this);
    argo <<"/Applications/MATLAB_R2008a/bin/matlab"<<"-nojvm -nosplash -nodisplay -r 'addmatrix(2,7)'";
    list <<"PATH=/sw/bin:/sw/sbin:/usr/bin:/bin:/usr/sbin:/sbin:/usr/local/bin:/usr/X11/bin:/usr/X11R6/bin";
    exec->setEnvironment(list);

    exec->start("/bin/bash", argo);

if there are a different mode more easy please write
