Membrane diffusion in a coupled reactor system can cause complex behaviour such as oscillations, period doubling and chaos. Here we study a simple model suggested by Deng-Harrison in 1969. The bifurcation diagram is obtained. We find good agreement with Figure 10 page 76 of the paper by Lengyel...

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...

Calculate the linear indices for neighboring points in a matrix. You need to supply one or more linear indices for the point(s) of origin and the dimensions of the matrix. You will get a list will linear indices to all neighboring points. The function also creates a vector with the distances from...
