实现广义预测控制代码。包含矩阵求逆、最小二乘法估计参数等功能性程序。代码中可手动设置预测长度及控制长度。-Generalized predictive control code. Contains the matrix inversion, least squares method to estimate the parameters of the functional program. Predict the length and control the length of the code

贪吃蛇代码实现，能够上下左右移动，吃掉其他的方块。当最后自己的长度占据频幕时可以自动终止-Snake code, can move around, eat other squares. Automatically terminate when the last length to occupy their frequency screen

Qt5下，采用QCustomplot控件绘制曲线，采用最小二乘算法拟合曲线，进行线性拟合，多项式拟合和指数拟合-Under Qt5, using QCustomplot control plotted using least-squares curve fitting algorithms, linear fit, polynomial fitting and exponential fitting

Suppressed carrier type differential phase modulation, Multivariate least squares fitting method of nonlinear equations, Numerical solution of differential equations method.
