Text In A Circle

calculates and plots the total density of photonic modes (DOS) allowed in a 1D photonic crystal with the unit cell made of two homogeneous dielectric layers; the calculation is separated in two cases: TE(s) and TM(p) polarizations; DOS is calculated via numerical integration of symbolic...

The velocity and shear stress versus radial position are determined for laminar flow of a power law fluid in a pipe. The shooting method is used to verify the no-slip boundary condition at the piped-deOaos wall. Once the velocity at the center is determined, the governing equation is solved...

calculates surface area A and its standard uncertainty uA for any arbitrary polygon in a plane given by coordinates x and y and their respective standard uncertainties ux and uy. The inputs are assumed to be VECTORS, x, ux, y and uy all should have the same size. The uncertainties are assumed to...

Given a desired value "y0", this function finds all the elements "y" in a vector whose values are the closest to "y0" in the whole vector, and also the positions "xi". So, the output is a set of points [xi,y0] given in two vectors, one for the values and another one for the positions.The inputs...

This program checks whether a point (x,y) lies inside,outside or on a circle defined by 3 other points.Syntax: iscircle(X,Y,x,y), where X=[x1 x2 x3] and Y=[y1 y2 y3]. Thus, a circle can be made out of these 3 points-->(x1,y1), x2,y2)&(x3,y3).Program checks whether point (x,y) lies inside,outside...
