%SPECTRALMUSIC Computes the frequencies and powers of sinusoids via the
% Spectral MUSIC algorithm.
% W = SPECTRALMUSIC(C,R,GRID,DOA_EPS) returns the vector of frequencies
% W of the complex sinusoids contained in the signal space defined by covariance matrix C.
% W is in units of rad/sample.
% R is the number of complex sinusoids.
% GRID defines the sensor locations: xcoord = real(grid), ycoord = imag(grid).
% DOA_EPS defines the stepsize for the search algorithm.
