Z = harmonicseries(AMP, PER, PHA, LEN, DIR, T, X, Y);
Performs the sum of harmonics:
z(t,y,x) = sum [ a*cos(k*x + l*y - w*t + theta) ]
a = AMP (amplitude)
k = K*cos(rdir) (x-component of wavenumber vector)
l = K*sin(rdir) (y-component of wavenumber vector)
K = sqrt(k^2+l^2) = (2*pi)./LEN (magnitude of wavenumber vector)
rdir = DIR*(pi/180) (direction of wavenumber vector in radians)
w = (2*pi)./PER (Temporal angular frequency)
theta = PHA*(pi/180) (Initial phase in radians)
This is useful when performing tests of Fourier Spectral Analysis, for example.
The program comes with the example on the screenshot.
