EMALGORITHM
In statistics, an expectation-maximization (EM) algorithm is a method for finding maximum likelihood or maximum a posteriori (MAP) estimates of parameters in statistical models, where the model depends on unobserved latent variables. EM is an iterative method which alternates between performing an expectation (E) step, which computes the expectation of the log-likelihood evaluated using the current estimate for the latent variables, and a maximization (M) step, which computes parameters maximizing the expected log-likelihood found on the E step. These parameter-estimates are then used to determine the distribution of the latent variables in the next E step.

fft_plot
routine to take the Fourier transform of a signal and plot both the time and frequency domain representations. Typical use:
>> n = 100 number of data points
>> dt = 0.01 spacing between samples
>> t = 0:dt:(n-1)*dt time vector
>> y = sin(2*pi*10*t) 10 Hz sin wave
>> fft_plot(y,dt) plot of signal in time and frequency domain
