Hi @Juan D Guerrero,
The “lowpass” function is not supported for code generation in MATLAB. You can use a different approach to implement the low-pass filter. “butter” function is a good alternative to the “lowpass” function, and it is also supported for code generation. Please run the following command to understand more about “butter” function -
doc butter
