MATLAB: Plotting frequency response from fdatool filter coefficients

fdatoolmagnitudephase

I created a 400 order bandpass fir filter using fdatool and exported the coefficients. How do I create the frequency response using the coefficients I just made?

The easiest way is to use the freqz function to display it. It will also calculate the frequency response and output it as a function of frequency. Use the phasez function for the phase.
