绘制在MATLAB 3D点 [英] plot a 3d point in MatLab

问题描述

我想绘制只是一个点在任何坐标系：直角，圆柱形或球形

I'm trying to plot just one point in any coordinate system: Cartesian, cylindrical or spherical.

我试过 plot3（1,1,1）有多个值，但只是显示在同一个位置，所有值一个小点！我试过冲浪（X，Y，Z）很好，但MATLAB说：ž必须是一个矩阵，而不是一个标量或矢量

I tried plot3(1,1,1) with many values but just shows a tiny point in the same location for all values! I tried surf(X,Y,Z) as well but matlab said: Z must be a matrix, not a scalar or vector.

感谢大家提前：D

推荐答案

这个怎么样呢？

plot3(1,1,1,'.');
grid on

你没有尝试，但话又说回来，这正是它！

you did try it, but then again, that is exactly what it does!
