Create a non isotropic 3D Gaussian PSFThe program takes three different standard deviation as input and creates a 3D non isotropic Gaussian distribution realted to it.Works faster with Statistical toolbox, but works fine without. Platforms: Matlab

THIS FUNCTION PROVIDES A USER A UTILITY TO PLOT THE BEAMPATTERN OF LINEAR ISOTROPIC ARRAYS BY PROVIDING THE INTER-ELEMENT DISTANCES,CORRESPONDING WEIGHTINGS AND/OR STERING DIRECTION OF THE BEAM. Platforms: Matlab

The Mogi [1958] model allows to calculate analytic solution for surface deformation due to a point source in an elastic half-space. This model is widely used to simulate ground deformation produced by local perturbation like volcanic magma chamber. It computes displacements, tilt and strain in a... Platforms: Matlab

variogram calculates the isotropic and anisotropic experimental variogram in various dimensions.Syntax: d = variogram(x,y) d = variogram(x,y,'pn','pv',...)The function uses parseargs (objectId=10670) by Malcolm wood as subfunction.Currently, the function calculates all variogram values at one...

Auto Gaussian & Gabor Surface fit---Functions to fit a 1D Gaussian to a curve and a 2D Gaussian or Gabor to a surface. The routines are automatic in the sense that they do not require the specification of starting guesses for the model parameters. This is done by evaluating the quality of fit for...

variogramfit performs a least squares fit of various theoretical variograms to an experimental, isotropic variogram. The user can choose between various bounded (e.g. spherical) and unbounded (e.g. exponential) models. A nugget variance can be modelled as well, but higher nested models are not... Platforms: Matlab

The feature vector is a 5(gray scale) or 15(colored) dimensional vector reflecting the contrast, texture strength and orientation and texture scale for each pixel. Texture scale is represented by the average speed of change of pixel intensity in a Total Variation framework while the texture... Platforms: Matlab

Purpose of this program is studying a not standard section subject to torsional stress. Not standard means the section is not included in engineering Handbooks. It can be studied with FEM analysis with commercial softwares, but sometimes this can become very rough.Fortunatly Prandtl theory of... Platforms: Matlab
