This program is the same as DATEVEC but rounds the seconds, so, eliminates the problem with the 60 seconds not rounded value. It uses DATAVEC and takes a little time while checking the date components..

[counter] = kMeans(numPoints, numClusters, shape, drawOn, showOn) This function takes as inputs: numPoints: the number of random points to cluster; numClusters: the number of clusters to group the points into; shape: a string 'square', 'circle', or 'tube' to carry out the kMeans process in; drawOn: a 1 or 0 indicating whether or not to show the points dynamically joining different clusters (not suitable for more than 500 points) ; showOn: a 1 or 0 indicating whether or not to show the update in clusters as a new figure after each iteration Given the appropriate parameters kMeans first places k = numClusters random points in the given SHAPE and then carries out the kMeans algorithm.

The proposed algorithm is based on nonlinear derivatives to automatically select the best edge information. This algorithm can replace the classical derivative with the following benefits: - univocal edge localization for synthetic and real images - noise reduction with no regularization: the noise level is weaker that the noise level in the original image - better direction estimation of the gradient - can product a confident edge reference map with synthetic images - extremely efficient on salt noise OR pepper noise (this last case needs a change in the nonlinear derivatives) - still noise reduction with regularized schemes (Canny, Demigny, .

OFDM Signal generation and decoding using QPSK as the modulation technique. This type of OFDM is particularly useful for WiMAX and other Wireless and Multimedia Standards. QAM4 and QPSK is same modulation technique. Just run the Model and with different SNRs in the Channel Block observe the performance of the OFDM.

The AWGN Channel Block in the Communications Blockset lets you specify SNR in several ways, including Eb/No. Sometimes people want to use a more itemized way of specifying the SNR, like the itemization found in a link budget. These two models show how to create equivalent implementations of a communication channel, one using the AWGN Channel block and the other using specifications for Transmitter Gain, Antenna Gain, Path Loss, and Receiver Noise Temperature.

If you pass in 2 vectors it returns the unnormalized distance between the vectors, the accumulated distance between them, the length of the warping path (the normalizing factor), and the warping path points. To compare 2 vectors A and B call: [Dist,D,k,w]=dtw(A,B) Dist is the unnormalized distance D is the accumulated distance k is the length of the warping path (the normalizing factor) w is a matrix containing the points along the warping path.

Statement: strLetterCounter('string') ....where, 'string' is an input string containing alphabet or numbers. Ex: string='aaaaaaaabbbbbbccd' Statement: strLetterCounter(string) Output: '8a,6b,2c,1d' Note: This function is different from the Matlab function called 'unique' because it keeps the order in which letters occur in the string.

This script demonstrates the influence of range reduction algorithm at low bitrate encoding using JPEG encode. The range [0-255] of pixel values is mapped to [64-235] in this script using a look-up-table. Subsequently, the file is compressed to achieve the same bit-rate (file size) as that of the compressed full range image.

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.
