方法很简单，只要将papersize固定就行了：set(gcf,\'unit\',\'normalized\',\'position\',[0.2 0.3 0.4 0.4])

如下面的程序用来绘制2800km处的S波层析成像，旋转以能够在各个视角看到其变化。

filename= \'map.2800km.xyz\';
a=dlmread(filename);
lat0=-90:90;
long0=-180:179;
dv=zeros(length(lat0),length(long0));
for i1=1:length(long0)
    dv(1,i1)=a(end,3);
    temp3=(i1-1)*(length(lat0)-2)+1;
    temp4=i1*(length(lat0)-2);
    dv(2:(length(lat0)-1),i1)=a(temp3:temp4,3);
    dv(length(lat0),i1)=a(end-1,3);
end

    view(i1,0);
    drawnow
    MOV=getframe(gcf);
        aviobj=addframe(aviobj,MOV);

end
aviobj=close(aviobj)
