利用MATLAB实现由经纬坐标向北京54坐标的转换。(Realize the use of MATLAB by latitude and longitude coordinates to Beijing 54 coordinate conversion.)

此程序利用“弦高法”控制得到曲线上若干点，然后推广到三维曲面上布点，可以按照曲面曲率变化得到点的布局，最终三维图上显示出来(This procedure using the chord method control curve of some points, and then extended to 3D surface distribution, can be in accordance with the change of surface curvature point layout, the final three dimensional graph display)

说明：  用matlab建立任意桁架模型，计算节点矩阵，约束矩阵等(Using matlab to establish any truss model, compute node matrix, constraint matrix, etc.)

基于PRBS码型产生QPSK和16QAM信号(QPSK and 16QAM signal generation based on PRBS code)

this code is for PCA function, used to reduce the dimension
