The toolbox can import spectra acquired on spectroradiometers manufactured by Analytical Spectral Devices (ASD), Spectra Vista Corporation (SVC), Ocean Optics and the Field Spectroscopy Facility (FSF). It can post process spectra to calculate spectral reflectance, radiance and irradiance. It also provides functions for spectral smoothing with a Savitzky-Golay filter and the removal of the spectral regions dominated by water absorption. Field...
On a Windows platform, MATLAB's XLSREAD and XLSWRITE open Excel as a COM automation server in the background to read/write data. Sometimes users want XLSREAD and XLSWRITE to do more, and would like their own custom XLSREAD or XLSWRITE functions...
This m-file computes an approximate determination coefficient (R2) for prediction, say
R2pred = 1 - (PRESS/SST)
where PRESS = prediction error sum of squares, SST = total sum of squares.
This statistic gives some...
An iterative method is presented for solving linear systems and linear least-square systems. The method is based on the Golub-Kahan bidiagonalization process. It is analytically equivalent to the standard method of MINRES applied to the normal...
Script to draw fractal trees generated from a given angle, distance factor and 'number of branches'.
'number of branches' - indicates how many child branches are born from each parent branch. 'angle' - determines how far...
This script simulates QPSK or 4-QAM modulation scheme in Rayleigh channel and compares it to theoretical limits.
QPSK gives 3dB SNR degradation when compared to BPSK but twice as much throughput.
I hope this will be helpful...
checkClass inspects the specified java object reference or class-name, and reports its superclass(es), new/modified methods, interfaces, enumerations, sub-classes and annotations.
This utility complements the more detailed UIINSPECT...
A uniform random number generator is used to generate the binary information sequence from the binary data source. The sequence of d-de?0d-deOaos and d-de?1d-deOaos is mapped into sequence of +E and d-deOCtE where E represents the signal...
The power spectrum measures how much information is contained at each spatial frequency.
Construction of the power spectrum takes three steps:
1) Get the 2D (fftshifted) power spectrum 2) Sample lines through sf=0 and...
This program simulates a nonlinear dynamical system and estimates the hidden state using particle methods.
The program compares the performance of 3 particle methods (particle filter, forward backward smoother (FBS),and Maximum...
BPSK SYSTEM SIMULATION We simulate the generation of random variables r0 and r1, which constitutes the input to detector. We begin by generating a binary sequence of 0?s and 1?s that occur with equal probability and are mutually...
Thus, this work offeres a sequential version of the LSI algorithm (SLSI). Its main difference from the existing algorithms is that the dimension of space is not fixed and dynamically changes to ensure a given level of relative...
The program searches for a girth 12 QC-LDPC code given size of sub-matrix, row and column weights. The configuration of sub-matrices could also be changed. The program offers flexibility in constructing girth-12 QC-LDPC codes compared to other...
This is a very simple method to find prime numbers. I use a mathematical function to find non prime numbers. Thus I have compared its efficiency with a code found on Matlab Central, Written by John D'Errico.
Basic examples of using trapz and quad to evaluate the integral of two simple known functions between defined limits.
A for loop is used to loop over the upper limits of integration. The results are compared to show the greater...
Realterm is a serial/tcpip terminal program which can be controlled from MATLAB to do serial comms, for example to log data from instruments etc. It is excellent for debugging difficult, (eg binary, serial data) with any software.
This function localizes a single source from a frame of data received at the microphones. It uses the Steered Response Power with the PHAse Transform (SRP-PHAT) as the functional. The true source location will have the maximum SRP-PHAT value....
This module provides a framework for easily creating searches on any entity known to Drupal, using any kind of search engine. The module on its own is pretty much useless and needs at least another module that defines an actual search backend...
The plane stress problem i.e a plate under uniform tension at its edges is solved. Plate is dicretized using isoparametric Q4 elements. Pre-processing is done using a standard FEM software. 2nd order Gaussian integration is used to get stiffness...
Pressflow Placement allows you to create blocks that hold a maximum, fixed number of content items. A "Place" tab appears on nodes that are eligible for placement into these blocks. Clicking on "Place" walks the user through... |
