Hi,
The error message you are seeing indicates that the function 'eml_max' is not recognized. This is because 'eml_max' is an internal function used by MATLAB's code generation process, and is not available for use in your MATLAB code.
Regarding your question about converting your MATLAB function into VHDL code using HDL Coder, it is important to note that not all MATLAB functions can be directly converted into hardware. Some functions may require modifications or simplifications to make them compatible with the HDL synthesis process.
In the case of the 'smoothdata' function, as you mentioned, it uses strings which are not supported in HDL Coder. One way to work around this limitation is to replace the 'smoothdata' function with an equivalent function that does not use strings. This may involve writing your own custom function or modifying an existing function to achieve the desired smoothing behavior.
Another option is to use a different smoothing technique that is supported by HDL Coder. For example, you could use a moving average filter or a Savitzky-Golay filter instead of the 'smoothdata' function.
It is also worth noting that even if you are able to modify your MATLAB function to make it compatible with HDL Coder, the resulting VHDL code may still require further optimization or modification to achieve the desired performance or functionality.
