动画剧情/轨迹在MATLAB /八度 [英] animate plot / trajectory in matlab / octave

问题描述

我试图用MATLAB /八度，我希望它盘旋了动画这种螺旋形或倒

I'm trying to animate this spiral using matlab / octave I want it to spiral up or down

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);

我试图用一个for循环动画，但只是给了我一个锥体形状见下图

I tried using a for loop to animate it but that just gives me a cone shape see code and image below

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

推荐答案

下面出现在八度3.6.2工作

The following appears to work in 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
