给三维矢量图按照不同高度设置箭头颜色

figure 
clf
X = surfaceuz(:,1);
Y = surfaceuz(:,2);
Z = surfaceuz(:,3);
hold on

zcolor = jet;
% q=quiver3(X,Y,Z,X,Y,W)
for i  = 1:length(surfaceuz)
    quiver3(X(i),Y(i),Z(i),X(i),Y(i), Z(i),...
        'Color',zcolor(floor((Z(i) - -0.1) * 255 / 0.35) + 1, :), ...
        'AutoScale', 'off')
end
