Transmission line length formula for coaxial cable to an antenna(the velocity factor for coax is approximately 0.66)frequency is in Mhz,length is in feet.
The function implement the 2D dyadic(Paley) ordered fast in-place Walsh-Hadamard transform, which can be used in signal processing, pattern recognition and Genetic alogorithms. This algorithm uses a Cooley-Tukey type signal flow graph and is...
Online Simulation of Brownian motion in 2d, 3d. Stock Simulation with EWMA, GARCH(1,1). One factor equilibrium interest rate model simulations, estimation and residual testing using Euler's appr. Monte Carlo option pricing with stochastic interest...
This program analyzes the performance of the AC voltage regulator operating on the Sinusoidal pulse width modulation principle under different loading condidtions.
The inputs are:
- The input frequency.
- The modulation...
UPPSALATOR is an electroosmotical oscilLATOR developed in UPPSALA by T. Teorell. Up to now oscillations were observed only at constant currrent. Oscillations at constant
voltage were considered earlier as impossible. This program demonstrates...
The program does interpolation or decimation on a given 1-d data in an array.
Given X with sampling rate Ft Hz and is used to generate another sequence Y with sampling rate Ft' Hz, then Sampling Rate ratio R is given by,
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), the warping path points and both warped input vectors.
The SumProductLab provides a set of basic factor nodes for building up a factor graph. One can try out ideas by instantiating the necessary constraint nodes, connecting them up, and giving some evidence. The sum-product (or belief propagation)...
You only have to run main01.m, is easy to change the composition and operating conditions. If you want to add new components just add the critical propeties and acentric factor. Also is possible to use binary interaction parameters differents to...
The model simulates a three phase Sinusoidal PWM rectifier. Applied Voltage, switching frequency and sampling factor can be changed from the model properties block.
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 function gives the decimation matrix which after post mulitpling it with the given signal gives the downsampled version of the original signal...
D = decimmtx(x,N)
decimates the given signal by a factor of N.
Compute 2D - MultiWall model
rs_amp = multiwall_model(TXpoint , RXpoint , walls , material , [L0] , [n]);
TXpoint Transmitter points (2 x Nt)
This is an OFDM simulation that gives you the PAPR, BER, and the PSD before and after the SSPA.
This simulation will ask you about the parameters to simulate them: length of OFDM symbol (N), upsampling factor (k), number of input bits...
It calculates the Tillson moving average. The user is able to change the parameters such as the smoothing sweeps and the volume factor
An image in your root directory can be zoomed by calling the above program.
*First try with a small image. Because when the image is smaller, program response quickly.
How to Run the Program
Same functionality as the MATLAB rref function, but quicker.
A = rand(200);
R1 = rref(A);
Elapsed time is 1.435837 seconds.
R2 = mex_rref(A);
Elapsed time is 0.012729...
Implementation based on:
"Finite-Element Discretization Of Static Hamilton-Jacobi Equations Based On A Local Variational Principle"
by F. Bornemann and C. Rasch
1. There is no restriction...
The 'im_rst.m' function rotates, scales, and translates an image according to the scale, rotation, and translation parameters passed to it.
'function rst = im_rst(I1, scale, angle, x_shift, y_shift)
I1 -> input image
This m-file is a three-factor analysis of variance design in which there are repeated measures on only one of the factors. In repeated measures designs, the same participants are used in all conditions. This is like an extreme matching. This...
