Cartesian points to solar coordinates
显示 更早的评论
I want to define a small plane in which 'x' changes from (0.5 to 49.5), 'y' changes from (0 to 4.8) and 'z' changes from lets say (2.5 to 4.4). Its like a small piece of a pitched roof placed at an angle of about 22 degrees. I want to get the Cartesian points (x,y,z) of each point in this plane to use them later in some formula to get its solar coordinates. Lets just say that I want to get the coordinates of one solar panel (black region) in the given figure.

What I have undestood from your question is- you have the x,y,z points for a plane.
Is there any issue to use
[theta,rho,z]=cart2pol(x,y,z)
for complete set of data.
You will get the sets of theta, rho and z data of polar plane.

I have to use a different formula to calculate the solar coordinates. I have been able to define the interested plane(figure and plot attached), the only thing left is how can I get the cartesian coordinates of each point in the highlighted region? Hope to hear back from you.

close all;

x = linspace(0.5,49.5,100);
y = linspace(0,4.8,100);
z = linspace(2.5,4.4,100);
[X,Y,Z]=meshgrid(x,y,z);
v = X.*Y.*Z; %Creating a volume region
% Data defining a surface
[xs, ys] = meshgrid(x,y);
zs = 2.5+(tand(22).*ys);%Defining the slope of the roof
% Slice along it
slice(X, Y, Z, v, xs, ys, zs);
