J. Chapman Original code % % Define variables: % g -- Microphone gain constant % gain -- Gain as a function of angle % theta -- Angle from microphone axis (radians) % Calculate gain versus angle g = 0.5; theta = 0:pi/20:2*pi; gain = 2*g*(1+cos(theta)); % Plot gain polar (theta,gain,'r-'); title ('Gain versus angle \it\theta'); 图 3.7 心形麦克风的增益图象
