说明：  最优化方法: 共轭方向法 matlab源代码 需要改变原函数及其梯度(Optimization: Conjugate Method need to change the original function and its gradient)

输入： 二维矩阵；输出：降维结果； 共包含34种降维方法，线性/非线性；局部/全局；监督/非监督(Input: 2-D matrix; output: dimension reduction result; contains 34 dimensionality reduction methods, linear / nonlinear; local / global; supervised / unsupervised.)

分别对正弦波，三角波，方波，一周期内取为整数的64个点（A=4095）；写锯齿波和方波的谐波构成（只写了3、4个）。(Of sine wave, triangle wave, square wave, A week off for integer in the period of 64 points (A = 4095) Write a sawtooth wave and square wave of harmonic (only wrote 3, 4).)

说明：  MATLAB程序，通过3维空间点插值，构建数字地图，可以根据调整点坐标自行构建数字地图。(MATLAB program, through three-dimensional space point interpolation to construct a digital map, you can adjust themselves to build a digital map based on coordinates.)

通过B-样条曲线将仅由三维空间中若干点构成的折线轨迹平滑成曲线轨迹，并可视化。可用于机械臂的运动控制规划。(Through the B- spline curve, the curve of the broken line formed by several points in the 3D space is smooth, and can be visualized. Motion control planning for a robot arm.)
