洋流的仿真matlab源码

%%
% This is an example of how to visualize vector fields with streamlines in MATLAB®. Vector fields contain vector information for every point in space. For example, air flow data inside a wind tunnel is a vector field.

% Read about the <http://www.mathworks.com/help/matlab/ref/streamline.html |streamline|> and <http://www.mathworks.com/help/matlab/ref/coneplot.html |coneplot|> functions in the MATLAB documentation.

% Create streamline
[sx, sy, sz] = meshgrid(min(x(:)), linspace(20, 40, 3), linspace(5, 15, 3));
hhh = streamline(x, y, z, u, v, w, sx, sy, sz);
hold on

% Plot start point of the streamlines

% Add velocity cones on top of the streamlines to indicate the velocity
% along the lines.

% Get X/Y/Z data for the stream lines
xx = get(hhh, 'XData'); 
yy = get(hhh, 'YData');
zz = get(hhh, 'ZData');

% Place 5 velocity cones per stream line
fcn = @(c) c(round(linspace(1, length(c), 5)));
xx = cellfun(fcn, xx, 'UniformOutput', false);
yy = cellfun(fcn, yy, 'UniformOutput', false);
zz = cellfun(fcn, zz, 'UniformOutput', false);

% Create coneplot
hhh2 = coneplot(x, y, z, u, v, w, [xx{:}], [yy{:}], [zz{:}], 3);
set(hhh2, 'FaceColor', 'r', 'EdgeColor', 'none')
