- Most probable path using Viterbi algorithm
- License: Freeware
- Price: 0.00

The submission considers a case where you deduce what weather it is given the status of a shirt that is hung outside. The weather could be Sunny, cloudy, Rainy and the shirt could be dry, dryish, damp etc. Now given some probability matrices (The initial probability of the weather, the transition probability of the weather and the observation given weather matrices), can the chain of weather be deduced? The Viterbi algorithm is used to decode the states.

- Sum of harmonics
- License: Freeware
- Price: 0.00

For several different reasons it could occur that we need to produce a signal from the sum of several harmonic components. In the usual case of Fourier analysis, FFT and IFFT are likely the best choice. However it could happen that: - The frequencies of the harmonic components are unevenly spaced - The time vector is unevenly spaced In such cases we could be in the need of coding the summation directly in Matlab, that is quite slow in performing this tasks.

For vectors, Y = RUNMEAN(X,M) computes a running mean (also known as moving average) on the elements of the vector X. It uses a window of 2*M+1 datapoints. M an positive integer defining (half) the size of the window. In pseudo code: Y(i) = sum(X(j)) / (2*M+1), for j = (i-M):(i+M), and i=1:length(X) For matrices, Y = RUNMEAN(X,M) or RUNMEAN(X,M,[]) operates on the first non-singleton dimension of X.

An LPC vocoder (Linear-Predictive Coder), is a lossy compression technique that is highly optimized for low-bitrate speech transmission. The problem here that we solve is to take a speech waveform with an 8kHz sampling rate, code it to a much lower bit-rate so that it can be transmitted over a channel, and finally decode it to a signal that is of the same quality.
