Curl Of A Vector Field

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...

Computes the distance 2-point correlation function of a finite 2D lattice. The functions is:[ coorfun r] = twopointcorr(x,y,width,height,dr)Where x is the list of x coordinates of lattice points. y is the list of y coordinates of the lattice points, width is the width of the lattice, height is...

Extracts the edges of a color image without converting it to grayscale.Changes in color are detected even when the grayscale color of two pixels are the same. The edge strength is typically greater or equal to the magnitude obtained by simply filtering a grayscale image.Optionally, the edge...

The standard problem of a Two Link Manipulator is developed both kinematically and dynamically. It is then controlled to trace a rotated ellipse. The non-linear terms (like gravity/inertia etc.) are exclusively canceled out in varying degrees and the performance studied.This file was created as a...

Easy method to estimate the pile forces of a pile system. The program is very fast to run. This gives the engineer the possibility to try out a couple of different designs of the pile system in a quite small amount of time. The pile system is also plotted with the forces acting on it. This does...
