Random sinusoidal signal generation with defined Amplitude and Phase

Write a MATLAB program to generate and display five sample sequences of a random sinusoidal signal of length 31

{X[n]} = {A · cos(ωon + φ)}

where the amplitude A and the phase φ are statistically independent random variables with uniform probability distribution in the range 0 ≤ A ≤ 4 for the amplitude and in the range 0 ≤ φ ≤ 2π for the phase.
