matlab/octave中的动画图/轨迹

Question

我正在尝试使用matlab/octave为这个螺旋设置动画我希望它能够向上或向下旋转

t = 0:0.1:10*pi;
r = linspace (0, 1, numel (t));
z = linspace (0, 1, numel (t));
plot3 (r.*sin(t), r.*cos(t), z);

我尝试使用for循环来设置它的动画,但这只是给我一个圆锥形状,请参阅下面的代码和图片

clear all, clc,clf,tic
t = 0:0.1:10*pi;
r = linspace (0, 1, numel (t));
z = linspace (0, 1, numel (t));

for ii=1:length(r)
    ii
    plot3 (r.*sin(t(ii)), r.*cos(t(ii)), z);
    hold on
    %pause (.00001)
end

Answer 1

以下内容似乎适用于 Octave 3.6.2

t = 0:0.1:10*pi;
r = linspace (0, 1, numel (t));
z = linspace (0, 1, numel (t));

figure
axis([-1 1 -1 1 0 1])
hold on

for ii=1:length(r)
    plot3 (r(ii)*sin(t(ii)), r(ii)*cos(t(ii)), z(ii),'*');
    pause (.001)
end
