Matlab Compiler and Unsupported Toolboxes

Hey everybody,

My code has syms and sym lines. But they can't compiled. How can i fix them? Are there alternatives ?

Example:

    syms x;
    f = get(handles.edit1,'String');
    k = str2double(get(handles.edit6,'String'));
  
    f_1 = diff(sym(f));
    f_2 = diff(sym(f_1));

Mathworks does not provide any alternative to this.

There is a third-party symbolic toolbox written in C++ that could be called upon by using loadlibrary(). It is a fair bit different than MATLAB's toolbox .

If you were to restrict what kind of functions the user could enter, then you could do your own string parsing and differentiation. This is relatively easy for true polynomials; it is not at all easy for things like the generalized 2F1 functions.
