In order to generate a sine wave in Matlab, the first step is to fix the frequency of the sine wave. For example, I intend to generate a f=10 Hz sine wave whose minimum and maximum amplitudes are and respectively. Now that you have determined the frequency of the sinewave, the next step is to determine the sampling rate.
