- Box Plot with Whiskers Plotted at Fixed Percentiles
- License: Freeware

Normally boxplot plots the whiskers with a maximum length based on the distance between the 25th and 75th percentile. This script uses boxplot but plots the whiskers for a specified percentile and only plots the outliers beyond the new whiskers. Note that the percentile is defined as the data point just beyond the calculated percentile. For example, if the 98th percentile lies between the 4th and 5th highest data points, then the 4th highest data point will be considered the 98th percentile, the whisker will extend to the 4th highest, and only the 4 highest values will be plotted as outliers..

- ZfitGUI(varargin) fits and simulates impedance data
- License: Freeware

The main features are: Plot. For each immitance types (Z, Y, C or M), the data can be plotted in the complex plane, as well their real, imaginary parts or their magnitude in function of the frequency (Log/Log). Simulation. The possibilities are almost infinite. Over the classical R, C, L electrical elements, one can use CPE (constant Phase Element) and even any user-defined element. Fit. ZfitGUI makes use of the simplex algorithm. One can put bounds to the parameters and vary the weight wich is defined in a matrix. Once a right model has been identified, the user would save time in using Zfit.

Newton number (also called the drag coefficient) and Archimedes number are plotted versus the Reynolds number for the laminar, transition and turbulent flow types using a log-log scale. A numerical example of the terminal fall velocity computation of a single spherical particle in a Newtonian fluid, for the turbulent flow type, is given in the program. For laminar flow, the terminal velocity expression is given by the well-known Stokes? law. Measurement of terminal fall velocity has important applications such as viscosity determination (e.g. falling-sphere viscometer) and decanter sizing. For a similar code using Mathematica 5.

This is a solution for the keplar problem for orbit insertion. Given a burn out velocity and a flight path angle, what is the apogee of the orbit, and the circular orbit that can be achived with one burn at apogee? The delta-velocity for circularization is also plotted. Several other planets , besides earth, are also included and the user can simple adjust the initial parameters to preform orbital analysis of several planets in our home solar system..

- 3D Array Factor of a 4x4 planar array antenna
- License: Freeware

3D Array Factor of a 4x4 planar array antenna calculated using general formulas and then plotted in 3D format. "AB" shows the excitation amplitude of the elements and "AB_phase" shows their phases. Elements are placed on the x and y axis and element factor is ignored. The code can easily be extended to larger general arrays..

- BER of BFSK in AWGN Channel
- License: Freeware

The MATLAB program simulates binary frequency shift keying (BFSK) at baseband through Monte Carlo method. The goal is to simulate bit error rate (BER) over an additive white Gaussian noise (AWGN) channel. For realizing that, the effect of noise is represented in the baseband with Gaussian random samples added to each signal sample. The signal to noise ratio (SNR) is varied to show the effect of SNR on BER. Finally the theoretical BER, i.e. Q(sqrt(SNR)) is also plotted to show the correctness of simulation..

- Baseline Fit
- License: Freeware

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. The selected points are indices into the column and may be specified explicitly ("pts") or interactively. Arguments following "y" may be in any order. To provide some noise immunity, "avgpts" determines the width in points for the calculation of the mean y(pts).

- EZFFT : An easy to use Power Spectrum (FFT)
- License: Freeware

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. In this latter case, T must be equally spaced (as obtained by LINSPACE for instance), and it must have the same length as U. If T is not specified, then a 'sampling time' of unity (1 second for instance) is taken. Windowing (appodization) can be applied to reduce border effects (see below). [W,E] = EZFFT(T,U) returns the power spectrum E(W), where E is the energy density and W the pulsation 'omega'.
