PCSA is a frequency domain analysis technique that can be used to transform PSDs (as those in a spectrogram) to the form of a two-dimensional histogram with frequency-magnitude bins. PCSA can be used to examine the spectral characteristics of a long period of data.

A stack-based sequential priority first decoder that returns Maximum-Likelihood solutions to spherical LAST coded MIMO system-type problems, i.e., a lattice decoder with spherical boundary control. In such problems, the depth of the search tree is known but the number of children per node is not fixed.

A stack-based sequential priority first decoder that returns Maximum-Likelihood solutions to M-QAM modulated MIMO system-type problems, i.e., a lattice decoder with optional justified rectangular boundary control. In such problems, the depth of the search tree is known and the number of children per node is also fixed.

This function calculates the probability under the normal distribution curve, plots the graph and the area calculated. Normaldistribution calculating the area under a normal distribution curve from -ve infinity upto point x. Input: x : point on the normal distribution curve mean : mean of the normal distribution curve sigma : standard deviation of the normal distribution curve (hint: normal dist mean=0, sigma=1) plotting: Plot the calculated area if plotting = 1 Output: area under the curve.

This program computes the projection of any n-dimensional vector y onto the canonical simplex Dn defined by Dn:={x: x n-dimensional vector, 0<=x<=1, sum(x(:))=1 }. Namely, it solves x=arg min_x |x-y| subject to the constraint that x is in Dn. Syntax: x = projsplx(y); Explanation of the algorithm can be found at http://arxiv.

This function displays the PSNR (peak signal-to-noise ratio) between two images. The answer is in decibels (dB). PSNR is very common in image processing. A sample use is in the comparison between an original image and a coded/decoded image. Typical quoted PSNR figures are in the range +25 to +35dB.

The function computes the psnr between two yuv videos. It considers the video signal as a whole and it doesn't average the psnr's of the single frames. You can compute the psnr between the Y, U, V or YUV parts of the yuv videos. The function supports different resolutions and the YUV-formats 4:0:0, 4:1:1, 4:2:0, 4:2:2 and 4:4:4.

Arterial blood pressure waveforms contain rich pathophysiological information; hence receive much attention in cardiovascular health monitoring. To assist computerized analysis, an automatic delineator was proposed for the fiducial points of arterial blood pressure waveforms, namely their onsets, systolic peaks and dicrotic notches.

UDP packets are used to send data from one computer to another over a network or from one application to another within a single computer. The py_udp programs enable Matlab to send and/or receive UDP packets. One Matlab session can communicate with another Matlab session (on the same machine or over the network) or it can communicate with a completely different program (again, on the same machine or over the network).

is program computes a map of visibility from a selected point on a topography. It has been written to help the search for radio relay best location. Because it considers only direct line of sight, it gives a good estimation for possible radio link for short distances only (less than 10 km), neglecting curvature of the Earth, Fresnel zone and atmospheric refraction on radio waves propagation.
