Call matlab function from Qt using QProcess - matlab

Question

I need to call Matlab function from Qt. I know that there are standard way to do it via Engine, but I was not able to connect .lib libraries (I think because I use Mingw compiler). So, as I understand QProcess is the only way to do it. I have studied examples and wrote simple program, which has one QLineEdit(for Matlab script) and two QPushButton (for send script to Matlab and read response). Here is code:
MainWindow::MainWindow(QWidget *parent) :
QMainWindow(parent),
ui(new Ui::MainWindow)
{
ui->setupUi(this);
proc = new QProcess(this);
proc->start("\"C:\\Program Files\\MATLAB\\R2013b\\bin\\matlab.exe\"");
}
MainWindow::~MainWindow()
{
delete ui;
}
void MainWindow::on_readButton_clicked()
{
QByteArray dataError = proc->readAllStandardError();
qDebug()<<dataError;
QByteArray dataOutput = proc->readAllStandardOutput();
qDebug()<<dataOutput;
}
void MainWindow::on_writeButton_clicked()
{
QString text = ui->textForMatlab->text();
QByteArray script;
script.append(text);
qDebug()<<script;
proc->write(script);
}
When I start that program matlab.exe is launching. But when I type something in QLineEdit and click write button there is no response from matlab. Could you tell me what I am doing wrong?

Answer 1

try this
QString program = "C:/Program Files/MATLAB/R2013b/bin/matlab";
QStringList arguments;
arguments << "yourarg" << "youragr2";// if u have any aruguments then pass here
QProcess *myProcess = new QProcess(this);
myProcess->start(program, arguments);
if it is not working then try with myProcess->startDetached(program,argumets);
