I have this simple system and I would like to get audiodata just like in Matlab. I have this error: Undefined function or variable 'getaudiodata'. Simulink cannot determine sizes and/or types of the output for block 'matrixtosound/MATLAB Function' due to errors in the block body, or limitations of the underlying analysis. Error in port widths or dimensions. 'Output Port 1' of 'matrixtosound/MATLAB Function/u' is a [30×1] matrix.
