An ADCARRAY object usually contains a memmapfile object, together with a scale and offset to convert the values stored on disc (and pointed to by the memmapfile object) to real world numbers which are returned as double precision. These can also be transformed by a function pointed to by a handle stored in the ADCARRAY object.

Everything was started some years ago - and the previous version was born 10x to dr. Ilia Iliev, technical University - Sofia and the modification of function "xcorr.m" by R. Losada included in the MATLAB 6.15 package. Unfortunately, I've erased the previous version by mistake so I am uploading again the new version.

With this program you can smooth your data automatically only by selecting the area to be smoothed with 2 clicks. Then INTERP1 is used to smooth. The operation is repeated until you press ENTER. Many other options are available. Like the use of BEZIER curves.

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).

Fast Algorithm estimating the number of sinusoids in a white Gaussian noise. This algorithm use a sub-space method based on chi-square statistics of eigen values of the Autocorrelation Matrix. Example : clear, close all hidden N = 512; L_vrai = 4; fe = 2000; F = (0:(fe/2)/(N/2-1):(fe/2)); snr = [-10 -10 -10 -10]; f = [25 230 500 780]; n = 32; prob = 0.

Sub band processing is based on splitting the frequency range into M segments (subbands),which together encompass the entire range. Each subband is processed independently, as called for by the specific application. The subbands are recombined after processing, to form an output signal whose bandwidth occupies the entire frequency range.

InPolyedron detects points inside a manifold closed surface (even non convex ones). The normal orientation is assumed to be outwards. Warning there is no check for closed surface or normal orientation, open surfaces will give nonsense results. In the limit of numerical accuracy, points lying on the surface will be considered in.

The programme here draws the plot of the periodic signal whose 'Ck' 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 function 3. Resolution 4. Range of k (it is actually -inf to +inf) we can only give suitable value for process to converge.

This scrip determines the column vector 'x', given the LU decomposition of matrix 'A'. It performs the forward substitution, finding 'y=L*z', then, by backward substitution: 'z=U*x', determines the values of 'x'..

Have you ever had a need to invert a matrix while out for dinner? Have you ever had the need to solve a second-order differential equation while stuck in traffic but didn't have access to Matlab? Well, now you can! This is a VBA module file (*.bas) that allows you to evaluate a string in Matlab by calling the Matlab interface.

The Linux Soft Real-Time Target is a target definition to Real-Time Workshop from Mathworks. The target uses the POSIX real-time clocks to generate periodic signals, to wake the model process at every time step. The process is changed to real-time highest priority defined by the scheduler, and therefore needs root privileges to execute.

Occasionally I see a request for computation of a running, windowed standard deviation. This is easily accomplished using filter and the alternative formula for the standard deviation: std = sqrt((sum(x.^2) - n*xbar.^2)/(n-1)). Movingstd allows you to specify forward, backward or central windows of any desired length.

This package consist of a number of auxiliary functions that are helpful for analysing 1D and 2D signals such as surface profiles and surfaces and images. They are all built upon the built-in MATLAB FFT routine for fast execution and they replicate (when it is existing) the result produced by built-in MATLAB function to some extent or completely.

This mex file implements vectorized FFTs on multiple threads. When a matrix is passed to FFTmt, it is divided in "numCPU" and each fraction of the problem is executed in a separate thread Example: if numCPU = 2 and the matrix has 256x2^14 elements, 128 FFTs are performed in each thread, allowing the OS to distribute the load on 2 processors.

"According to the U.S. National Highway Traffic Safety Administration, single-vehicle road departures result in many serious accidents each year. To reduce the likelihood of a vehicle's straying out of lane, automotive engineers have developed lane tracking and departure warning systems that use a small camera to transmit video information about lane markings and road conditions to a microprocessor unit installed on the vehicle.
