一个有趣的人走动程序，很有趣的。。。。。。(One interesting people walking program, very interesting. . . . . .)

根据M值的改变可以产生2、4、8、16PSK数字调制基带信号，且成形滤波器可任选升余弦、根升余弦、高斯。(M may be generated according to a change value 2,4,8,16PSK baseband digital modulation signal, and optionally raised cosine shaping filter, the root raised cosine, Gaussian.)

医学中用Matlab实现头颅等的三维重建(Medical implementation using Matlab and other three-dimensional reconstruction of the skull)

采用两种不同的数学方法进行处理。推导出两对角线方程和块状两对角线方程,提出了两种相应的数值计算方法。本文的方法具有对初值要求不高和收敛迅速的特点(The model equations of the multicomponent multistage adiabatic flash process are handled by two different mathematical methods in the forms of di-diagonal matrix equation and block di-diagonal matrix equation, and the two new algorithms are developed. The numerical calculation shows that the new algorithms process has the features of being more rapid to convergency and less sensitive to the initial values)

常规PID控制器主要采用模拟PID控制器。这种控制器的控制规律是：根据给定值和输出值构成的偏差按比例、积分和微分通过线性组合构成控制量，对被控对象进行控制。(Conventional PID controller is used mainly analog PID controller. This controller is the control law: according to the given value and output value constitutes a deviation by proportional, integral and differential form by a linear combination of the amount of control, control of the controlled object.)
