chebyshevT in a standalone app

Hi,

I created a standalone app that is supposed to use chebyshevT (Chebyshev polynomials of the first kind). Unfortunately it doesn't work as I get the message "Unrecognized function or variable 'chebyshevT'" while operating my app in testing mode. Any clue on how to fix this?

Thanks.

The chebyshevT function is part of Symbolic Math Toolbox. Looking at the Support for MATLAB, Simulink, and Toolboxes page for MATLAB Compiler, the entry for Symbolic Math Toolbox for MATLAB Compiler states in part:

Supported:

MATLAB functions, Simulink, and Simscape blocks created from symbolic expressions using matlabFunction, matlabFunctionBlock, and simscapeEquation.

Not Supported:

Creation of symbolic expressions such as using sym, syms, and str2sym.

Depending on what you're trying to do, one potential solution could be to compute the solutions to your equations in MATLAB, convert them to MATLAB functions using matlabFunction, and use the generated MATLAB functions in your application.
