The velocity and shear stress versus radial position are determined for laminar flow of a Carreau 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 Differential Algebraic...

A simple level control model with an output that is continuously visible in a Figure

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...

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...

>> Y = cummean(X,DIM);if X is MxN, Y is also MxN. To illustrate the functionality, lets assume X is a 1xN vector. Then, Y is a 1xN vector where the n-th entry in Y is given by mean(X(1:n)). So, Y(end) = mean(X), and Y(1) = X(1). cumvar works in the same way, and this can be done on an arbitrary...
