Convenience Sampling

A Simulink model that generates and displays a simple cosine wave. The model computes the cosine function using the continuous phase method, which is based on Euler's formula for the complex exponential. The cosine generator is provided as a subsystem, which the user can copy-and-paste into other... Platforms: Matlab

This implementation is flexible, with variable no.of antenna elements, the element spacing, tap spacing, sampling time etc. One can study the performance of the beamformer for different values of these parameters. Platforms: Matlab

[FDOUT, FREQ_AXIS] = FDCORR(A,B,FRANGE)FDCORR Joint frequency and delay correlation Performs an efficient circular cross correlation between two vectors over all possible frequency offsets (Dopplers) between -pi and pi where 2pi is the sampling rate.A: vector representing received signal sampled... Platforms: Matlab

EZFFT(T,U) plots the power spectrum of the signal U(T) , where T is a 'time' and U is a real signal (T can be considered as a space coordinate as well). If T is a scalar, then it is interpreted as the 'sampling time' of the signal U. If T is a vector, then it is interpreted as the 'time' itself.... Platforms: Matlab

The programme here draws the plot of the periodic signal whose d-deOaoCkd-de? is given by user.Following data should be entered by user.1. Ck value (separate for k=zero, k= even and k=odd)2. Time period of periodic function3. Resolution4. Range of k (it is actually -inf to +inf) we can only give... Platforms: Matlab

This tool enhances signal detection for broad-mass TOF spectra by accounting for changing peak width and providing peak-shape-dependent filtering capabilities. A set of input TOF spectra is processed to produce aligned peak list and array of corresponding signal intensities. Signal processing... Platforms: Matlab

This function opens a figure on screen. While in the figure, mouse button toggles the function on and off. While ON, the function samples and filters the mouse current location (in Realtime), and present both original and filtered points.This function was created as a routine University homework....

The model simulates a three phase Sinusoidal PWM rectifier. Applied Voltage, switching frequency and sampling factor can be changed from the model properties block. Platforms: Matlab

This GUI was designed to help users to better understand the Undersampling/Bandpass Sampling technique. While you're urged to follow the above link, to better understand this topic, a brief explanation follows:All of us, dealing with signal processing are familiar with the Nyquistd-deOCtShannon...

The model simulates three phase inverter with symmetric PWM modulation in which reference is sampled at the positive peak of the carrier and is held constant till the next positive peak of the carrier appears. The model demonstrates symmetric regular sampling at positive peaks of carrier and... Platforms: Matlab

[INFO, DATA] = ACQREAD(FILENAME) reads the content of the AcqKnowledge file specified in the string FILENAME. INFO is a structure containing the metadata (header, markers, etc.). DATA is a cell array, indexed by the channel number, containing the acquired physiological signals.[INFO, DATA] =... Platforms: Matlab

Raw MRI data are generated analytically from k-space coordinates using the (continuous) Shepp and Logan head phantom function. K -space coordinates are typically entered as 2D matrices (frequency and phase encodes).This tool is ideal for testing reconstruction of non-linear k-space trajectory MRI... Platforms: Matlab

The integration is performed via a FFT. Thus it is important for... Platforms: Matlab

Standard GLCM textural analysis often doesn't give good results unless a large number of global classes are used (and using a large number of classes brings other problems). Using local classes helps, but the results are sensitive to noise. This program uses unweighted area sampling to vastly... Platforms: Matlab

MOTIFINFO = GIBBSMOTIFSAMPLER(SEQARRAY,MOTIFVECTOR,ALPHABET,OPTIONS) Searches for the motifs in a set of sequences via Gibbs sampling. seqArray is a cell vector of sequence strings. motifVector is a vector of uniformly-spaced motif widths you wish to optimize. The program iterates over these... Platforms: Matlab

This code reads EEG data of specified length from a specified 'bdf' file. It is easier to use than traditional bdf readers and does not output some unnecessary (from author's point of view) information, such as sampling frequency for EACH EEG channel. All EEG channels are assumed as sampled at... Platforms: Matlab

Closes and deletes all instruements.Very useful when debugging instrument control applications since you would need to reset matlab in order to clear these devices.For convenience you may want to put it with the functions from the instrument control toolbox. Platforms: Matlab
