This script plots the polarization Stokes vectors (S1, S2, S3) on a Poincare sphere. See "Polarized Light" by Collett (publ. Dekker) for a background on the optics.

Type "poincare" at the Matlab prompt and a graphical window should pop up. Enter an input data file in the GUI, then lick "Plot". You can also save the output graph to a .jpg file.

The input data file format can be modified to...

FSSF2 fit a 2-D fourier series surface over scattered 3D data. Series formulation may be altered optimization fit also available. The gui is pretty self-explanatory. Enjoy!

Bidimensional surface shift to a position specified by a vector [x,y].

How do you turn a collection of XYZ triplets into a surface plot? This is the most frequently asked 3D plotting question that I got when I was in Tech Support. This submission explains how.

Given a 3-d scalar function in terms of x,y,z the fielder.m function returns matrix of 3-d coordinates and uses the surf() function to create a 3-d plot of the surface. The field_test_script m-file can be executed to make using the function easier...

a gui which allow measuring an areas size and a paths length on an image (map).

You can calibrate the image scale.

You place points using left mouse button and remove points & areas with right mouse button.


These programs were developped to exploit luminance or BRDF data from the EZ-Contrast instrument developped by Eldim. They are applicable to any measurment done using a ccd sensor.

The developped library includes:
- maxima...

The program is an ordinary m-file
the matrix g(*,*) can be used to punch in the metric values in terms of symbolic variables x1,x2,x3,x4(co-ordinate axes)
The program first computes the Affine connection(Christoffel symbols) stored in...

Animation of the retrograde surface particle motion of a Rayleigh wave.
This is a simple animation of the surface particle motion of Rayleigh waves. Retrograde motion is evident.

Main purpose of this problem is drawing the orthotomic surface of a bezier surface through about arbitrary source point.

First of all you should gather the information from your solar panel datasheet/manual:
1)Short Circuit Current
2)Maximum Power Point Current @ STC
3)Open Circuit Voltage
4)Maximum Power Point Voltage @ STC

CYLINDER: A function to draw a N-sided cylinder based on the
generator curve in the vector R. It is based on file exchange 5468. I changed a little bit so that it can generate more points on the surface of the cylinder.

This package contains a set of routine for read, plotting, and editing the input and output of the DIAGNO synthetic diagnostic routine (used for calculation of magnetic diagnostic responses for a given VMEC equilibrium). This includes a routine...

Simulation of a gaussian pulse propagated in free space through 1000 um, using finite differences.
Just run the script and you'll get a surface which is made up of the pulse propagated at 1 um steps.

Based on Ken Elder's 1993 paper: "Langevin simulations of nonequilibrium phenomena" Computers In Physics, vol. 7, no. 1, 1993, p.27-33.

Domains of ordered phase are created from an initially disordered phase due to thermal...

COPYAXES copy an axes object into another axes object


COPYAXES(..., isInSubplot) - if the destination is in a subplot figure

FDSURFFT computes fractal dimension (slope) of surface image im and draw rose plots of slope and intercept.

We compare computed temperature distributions using both pdepe and analytical solutions for different geometries (slab, cylinder and sphere). Solids are kept initially at uniform temperature. For t>0, the boundary surface is kept at constant...

Optimisation for 4 variables using Genetic technique. Was designed to optimise surface impedance measurements

This function will display an image in a 3D plane with the specified position, image normal, image x direction and scale.

It is mainly a convenient wrapper for the surface function.
