在MATLAB中绘制三维核密度图(kernel density plot)需要几个步骤,包括准备数据、计算核密度估计和绘制图形。下面我将分点详细解释这一过程,并提供相应的代码片段。 1. 准备三维数据点集 首先,我们需要有一组三维数据点。这些数据点可以是随机生成的,也可以是实际测量得到的数据。 matlab % 生成示例三维数据点集 numPoin...
MATLAB Online에서 열기 Hi, I used this to generate a kernel density estimation plot: [f,xi] = ksdensity(myvector); figure plot(xi,f); How can I insert three vertical lines in the plot representing the median and 1st & 3rd quartiles?
MATLAB 代码实现如下：% Kernel Density Estimation % 只能处理正半轴密度 function [t, y_true, tt, y_KDE] = KernelDensityEstimation(x)% clear % x = px_last;% x = px_last_tu;%% %参数初始化 Max = round(max(x)); %数据中最⼤值 Min = round(min(x)); %数据中最⼩值 Ntota...
