matlab dsp(1． 利用自相关函数法和周期图法实现随机信号的功率谱估计。 2． 观察数据长度、自相关序列长度、信噪比、窗函数、平均次数等对谱估计的分辨率、稳定性、主瓣宽度和旁瓣效应的影响

该matlab程序实现字母T和L的区分，在9*9格形框里，字母T和L有不同的位置，任意位置，神经网络都可以识别出是T还是L(The program matlab and distinguish letters L, T, in the grid-shaped box 9* 9, the letters L and T have different locations anywhere in the neural network can identify a T or L)

图像腐蚀程序,希望能够帮助大家对图像处理的学习。(Image corrosion program, we hope to help everyone learn image processing.)

Univercity of Bristol几个学生用6DOF（也即是GY-521三轴加速度+三轴陀螺）制作的测步器，可以看到他们成功测量出各轴旋转以及xyz轴的位移(Univercity of Bristol several students 6DOF (that is, GY-521 triaxial accelerometer+ triaxial gyro) produced measured steps, you can see their success measurement of the displacement of each axis and xyz axis)

说明：  用课件方式教你对matlab有快速而全面的认识(Teach you quick and comprehensive understanding of matlab )

阻尼牛顿法求解minf(x)=(1-x1)^2+2*(x2-x1^2)^2初始点x=(0,0)精度为0.01。可运行出结果,程序清晰,算法明确。(Damped Newton method for solving min f (x) = (1-x1) ^ 2+2* (x2-x1 ^ 2) ^ 2 the initial point x = (0,0) accuracy of 0.01.It Can run out the results 。 the program is clear, algorithm is explicit. )

利用Matlab生成GPS C/A 码的基带信号。 （1）产生卫星PRN 号码为“5”的一组C/A 码； （2）循环生成25 页的导航数据，GPS 时间可填入一固定的已知数值； （3）生成C/A 码扩频信号，每个C/A 码码片给出4 个采样数据； （4）基带信号采用方波信号，电平为0 和1，占空比为50 ％， 不加入噪声，进一步生成某个特定的中频信号(The baseband signal is generated using Matlab GPS C/A code. (1) generate satellite PRN number " 5" is a set of C/A code (2) loop generates 25 navigation data, GPS time can be filled with a fixed known value (3) generated C/A code spread spectrum signals, each C/A code chip sample data is given 4 (4) a baseband signal using a square wave signal with a level of 0 and a duty cycle of 50 , the noise was not added, and further generates a a specific frequency signal)
