Error 1050 Occurred in MATLAB® Script Node: Complex Values Cannot be Converted to Chars

Secondary Software: LabVIEW Toolkits>>Math Interface Toolkit

Problem:
I'm trying to provide a MATLAB® Script Node with a path or string. I get run-time "Error 1050 occurred at LabVIEW: Error occurred while executing script. Error message from server:??? Error using ==> char. Complex values cannot be converted to chars. Possible reason(s): LabVIEW: Error occurred while executing script."

I can run the Fractal example just fine, but I get the same error when I try to Lorenz Diff Eq.

Solution:
The MATLAB® Script Node has improperly converted the array from real data to complex data. You can use additional commands in the MATLAB® Script Node to properly format the data into a character array. Consider the following example.

The input a is configured as a Real Vector.

However, if you open the MATLAB® Workspace Browser from the Command Window in the MathWorks Inc. MATLAB® software...

You will see that the actual data type of the variable is complex.

To fix this, you can add two additional commands (real and uint8) to the MATLAB® Script Node that convert the data to the real type compatible with the char function.

The correct data type for the char function is reflected in the Workspace Browser in the MATLAB software.
