这对于学习matlab是非常有用的，是相当有用的。要相信的(This is very useful for learning matlab is quite useful. To believe)

高阶谱分析工具箱（HOSA）中choices函数。(HOSA tool box s demo will call a function name choices. Copy this file to one of your MATLEB search path to fix the choices problem. )

qdpsk调制，含子程序，qdpsk调制(qdpsk prepared, containing subroutine)

鼠标游戏仿真，可模拟鼠标在图像上游走的轨迹，对MATLAB代码进行示例。(Mouse game simulation, can simulate the mouse on the image migration trajectory of MATLAB code examples.)

说明：  利用matlab强大的数值计算和绘图功能解决了在求解正弦稳态电路时存在的困难。 关(Using the powerful numerical calculation and drawing function of MATLAB, the difficulties in solving the sinusoidal steady-state circuit are solved. shut)

说明：  此程序给出信号的多分辨率分析（Multiresolution Analysis），即信号的多分辨率分解（Multiresolution Decomposition）方法及应用。该程序是一个多抽样率系统（Multirate System）举例，用M个的滤波器，将信号的频谱等分成M部分，使所得抽样频率降为1/M，然后再依据它们的“重要性”给一不同的bit数，那么所传输的bit流必然会进一步下降，起到压缩带宽的作用。(This program gives the signal of the multi-resolution analysis (Multiresolution Analysis), the multi-resolution signal decomposition (Multiresolution Decomposition) method and its application. The program is a multirate rate system (Multirate System) example, with M a filter, the signal' s frequency spectrum is divided into M parts, the proceeds of sampling frequency reduced to 1/M, then according to their &quot importance&quot to the bit of a different number, then the transmitted bit stream is bound to decline further, to play the role of bandwidth compression.)

For example, heating up the temperature in a room is a process that has the specific, desired outcome to reach and maintain a defined temperature (e.g. 20°C), kept constant over time. Here, the temperature is the controlled variable. At the same time, it is the input variable since it is measured by a thermometer and used to decide whether to heat or not to heat. The desired temperature (20°C) is the setpoint. The state of the heater (e.g. the setting of the valve allowing hot water to flow through it) is called the manipulated variable since it is subject to control action

matlab鼠标在画板移动自由画图，画的线不会断续(Matlab mouse drawing in the drawing board move freely, painting line will not be interrupted.)
