Listing of Communication in Scripts

This a very simple function that produces a condensed, approximate version of the time-series signal y, with each group of n adjacent points in y replaced by its average. You can use this to condense over-sampled signals so that subsequent processing will be easier and faster.

Baseline Fit each column in "x". There did not seem to be a similar function in th file exchange. This routine is simply a wrapper for two Matlab routines, interp1 and ginput. Syntax: [ycorr,yfit] = bf(y,pts,avgpts,method,confirm); ycorr = bf(y); ycorr = bf(y,method); A baseline fit is interpolated from selected points and then applied to the data.

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.

Weighted Median Filter: It is same as median filter, only difference is the mask is not empty. It will having some weight (or values) and averaged. The steps to perform weighted median filtering are as follows: 1) Assume a 3x3 weighted mask. 2) Place the mask at the left hand corner.

This function is written to understand and/or explain an fft algorithm and usage of radix2 procedure. This function take the signal which you want to find FFT, for m bit you can also call the function without entering a signal or number of points, because there is default values for y and m which are; y = sin(2*pi*50*t)+sin(2*pi*120*t); m=3; you can see the steps of order reversing used as built-in function but non others.

This function generates Walsh Codes. The difference between this function and other functions available to generate walsh code is : 1. you can call this function directly in your script, you will have to pass only the value of 'a' (length of code is 2 ^ a) 2.

This example using Matlab commands to access Simulink Signal properties to easily create a batch file that can log almost any Simulink signals. This is very useful for batch testing when the parameters in the Simulink model are set in a m-file. It helps to reduce the use of Save-To-Workspace blocks.

The file calculates and plots FM noise sidebands for a carrier. It also does sinusoidal modulation. This simple way of adding noise to a carrier is useful for simulation of PLLs. It turns out, though, that the mean of the randn function is not as close to zero as it could be, and this causes the fft to generate extra sideband energy, which makes it appear as if the noise is not what would be expected.

This function convolves two very large vectors very quickly. Enormous gains in speed are due to the use of two fft's and an ifft. To find out how to use this program, put it in you 'work' folder and type "help fconv"..
