WebFirstly, bode plot Matlab is nothing but plot a graph of magnitude and phase over a frequency. For that, first, we need to create one transfer function. For creating a transfer function, we need to know the numerator and denominator coefficients of that transfer function; we create the transfer function in two ways. The ways are as follows:-
