matlab从入门到精通第9章书后源码对初学者很有帮助

% create_obj_handle.m
% 创建图形对象句柄函数
x=-2*pi:0.5:2*pi;
y=x;
[X,Y]=meshgrid(x,y);
Z=X.^3/2-Y.^3/2;
% 创建坐标轴句柄对象
Ha_axes=axes('color',[0.8 0.8 0.8],'xtick',[-8:2:8],'ytick',[-8:2:8])
% 绘制图形
Ha_surface=surface('xdata',X,'ydata',Y,'zdata',Z,'Facecolor',get(Ha_axes,'color')+0.1,...
    'edgecolor','k','marker','o','markersize',3)
