matlab中怎样使图变得圆滑答:如果这样的话很明显样条插值是合适的。例子:x=[520,280,156.6,78,39.62,3.1,0];y=[0,-30,-36,-35,-28.44,-9.4,0];x2=520:-10:0;y2=spline(x,y,x2);plot(x2,y2,'bla');hold on;plot(x,y,'--rs','LineWidth',2,...'MarkerEdgeColor','k',...'MarkerFaceColor'...
如何用MATLAB绘制椭圆?答:例子:Create and plot the small ellipse centered at (0º,0º), with a semimajor axis of 10º and a semiminor axis of 5º.axesm mercator ecc = axes2ecc(10,5);plotm(0,0,'r+')[elat,elon] = ellipse1(0,0,[10 ecc],45);plotm(elat,elon)在MATLAB...
