Using parfor for reflection function
显示 更早的评论
Hi! I have light rays and their points (x0, y0, z0; x1, y1, z1; ) I want to apply parfor for calculation of reflection (x, y, z) for each point, and for end point (x, y, z ). Reflection points (x, y, z) of the first reflection will be the starting point for the next one, and so on. I am really absolutely new in Matlab. Here is my draft. And also I will calculate length of the ray (using Pythagorean theorem) Thank you for your help in advance
function [x,y,z] = reflection(x0, y0, z0, theta ... )
% Detailed explanation goes here
outputArg1 = inputArg1;
outputArg2 = inputArg2;
end
% number of reflection
Bk = 6;
parfor ii=1:Bk;
for ii = 1:5
x(ii), y(ii), z(ii) = reflection(x0,y0,z0, theta(ii))
length of the ray (using Pythagorean theorem)
% Ray1 1.5, 0 ,0
x0 = 1.5;
x1 = 1.5;
y0 = 1.5;
y1 = 0;
z0 = 3;
z1 = 0;
% length of ray
d1 = sqrt((x1-x0)^2 + (y1-y0)^2 + (z1-z0)^2);

You define a function. Inside the function you use parfor. Inside the function you call itself recursively. That would attempt to invoke parfor within the existing parfor, which is permitted but would treat the inner parfor as a plain for loop.
You do not have any termination test on your recursion so the function is going to invoke itself over and over again until you exceed the stack limit and generate an error.
