This function will rotate a a 2nd rank spherical tensor using reduced Wigner rotations.
Chemical shift anisotropy is often described by a 2nd rank spherical tensor in the Principal Axis System(PAS):
R(2,m)(PAS)=sqrt(3/2)*aniso*[-sqrt(6)*eta/6 0 1 0 -sqrt(6)*eta/6]
This tensor will be described in the laboratory frame (LAB) by applying some wigner rotations, e.g.
As input data, one has
A: a 2xN or 3xN matrix whos columns are the coordinates of N source points.
B: a 2xN or 3xN matrix whos columns are the coordinates of N target points.
This code solves biot savarts law to evaluate magnetic field from a circular coil at all points in the plane which is perpendicular to the plane of the coil.
coil is situated in the X-Y plane centered at origin having radius =6 and we want to...

This function creates a 3D stacked block drawing of a binary mask by drawing square patch objects at each face of the mask which borders empty space. It is similar to isosurface, and useful for visualizing a 3D binary mask in its entirety (with no...
Trying to visualize a huge triangulation with trisurf or triplot is often very slow and frustrating. Solution : use Paraview, a very powerful and free 3D data viewer. But it could be complicated to generate the input file specially with binary...
This is a GUI for DTMF generator-decoder using Goertzel's algorithm.Has options to change Number of samples and Noise power that could be added at the generator.Suggestions and comments is always welcome.Now i am working on medical image pattern...
vectline is "vector field line plotter". Depending on the dimension of coordinate axis, vectline can plot both 3D and 2D vector field line.
Example for 2D field
>> syms x y
>> F = [-y, x];
I was playing the game Scramble on my iPod touch, and I realized that I wasn't very good. But the algorithmic challenge of writing a program to solve the Scramble (same as Boggle) game was too tasty to pass up. It was indeed quite challenging, but...
Computes the Gaussian function in 1D:
x = Co-ordinate
x0 = Centre of function
FWHM = Full Width Half Max of the function
order = Gaussian order
Simple gui widget to get the coordinate change between two points.
just type getdelta and a button with three fields will appear. click the button and then two points in a plot. The change in x, change in y, and slope will be...
