GUI Deployed into EXE is not working propaply

Hi Everyone,

I used the deploytool command to build a stand alone application (EXE),

The GUI is working well, but the EXE file doesn't work completely.

The problem occures when I use the button that performs the following commands:

 syms T  
    fun1=(b(1)*T+(b(2)/2)*T^2+(b(3)/3)*T^3+(b(4)/4)*T^4+(b(5)/5)*T^5+b(6))*(8314/Mw)-handles.metricdata.Enthalpy;
    f1=inline(fun1);
    fun2=(a(1)*T+(a(2)/2)*T^2+(a(3)/3)*T^3+(a(4)/4)*T^4+(a(5)/5)*T^5+a(6))*(8314/Mw)-handles.metricdata.Enthalpy;
    f2=inline(fun2);
    z1=diff(fun1); % = Cp 1st species for T<1000
    z2=diff(fun2); % = Cp 1st species for T>1000
    f3=inline(z1);
    f4=inline(z2);
    T0= str2double(get(handles.text6,'string'));
    T=T0;
    for i=0:inf %Newton Raphson Method
        x=T;
        if T<1000
        T=x-(f1(T)/f3(T));
        else
        T=x-(f2(T)/f4(T));
        end
        if abs(x-T)<0.001 %Tolerence
            break
        end
    end

I Think the problem is in the For loop that extends from 1:inf!!

Because its too large, but it works well in the GUI file!!

Any help is appreciated.

Hello, same problem here, this has to do with the syms, did you get to solve the problem?

Do you even need T to be declared syms? Just leave out that line and see if it works. It looks to me like T could just as well be a regular numerical variable and work fine.

Catarina, the symbolic toolbox can never be compiled. You should use a program to calculate the formula symbolically, and you should use matlabFunction() with the output file option to have it write a file of MATLAB code that implements the formula in non-symbolic form. Then your compiled GUI would call upon those function files, never using the symbolic toolbox itself.

Yes, if you look around, you can find C++ projects to do symbolic computation that you could link to from your MATLAB code. The facilities offered by the projects varies a lot. For example some of them only offer basic extended precision addition subtraction multiplication division, and trig and logarithms, but others have some degree of calculus or linear algebra.

However, you will not find the full MATLAB Symbolic Toolbox, and there is no possibility at this time of convincing Mathworks products to compile functions from the Symbolic Toolbox.

As I wrote above,

"You should use a program to calculate the formula symbolically, and you should use matlabFunction() with the output file option to have it write a file of MATLAB code that implements the formula in non-symbolic form.

The Symbolic Math Toolbox cannot be deployed:
