extract Object properties from cell array
显示 更早的评论
I have a cell array where each cell is a .NET object called Centroid. It has the following structure.
u.centers{:}
ans =
Centroid with properties:
x: 112.5769
y: 29.5762
count: 1250
strength: 12.3399
ans =
Centroid with properties:
x: 21.5000
y: 18.0690
count: 58
strength: 12.3400
I would like to plot the x,y values. How do I go about extracting the x and y values for a plot. This was my naive attempt:
plot(u.centers{:}.x, u.centers{:}.y, 'r.');

This should work:
xy = cell2mat(cellfun(@(c) [c.x; c.y], u.centers, 'UniformOutput', false));
plot(xy(1, :), xy(2, :), 'r.')
