这是一个求盒维数的Matlab程序，具有简单易求的功能(This is a box-counting dimension for the Matlab program, with simple and easy for the function of)

说明：  用matlab将hanning窗、hamming窗、Blackman窗画在同一个图中。语音分帧，加窗，短时能量，短时过零率，端点检测(Using matlab to hanning window、hamming window and Blackman window draw in the same graph.Voice sub-frame, add windows, short-term energy, short-term zero-crossing rate, endpoint detection)

用matlab编写的线性卷积和FFT，与matlab自带函数功能一样。每行代码都有注释，便于拓扑和扩展(Linear convolution and FFT using matlab matlab own function function. Each line of code is well commented, easy topology and extended)

自己做的pid调节，已知输入求输出过程用的是龙格库塔发的4阶程序，对了解rk4有很大帮助(Do the PID regulation, the known input process is the output of 4 order Runge Kutta procedure development, are of great help to understand RK4)

出一种实现不同维间估计结果自动配对的二维频率估计算法。首先把二维频率估计问题转化成两个矩阵束的特征值问题。根据矩阵束的特征求出两个矩阵束的公共特征向量，并以此为基础同时求出两个矩阵束的特征值。算法估计误差与现有算法相近，但解决了现有算法普遍存在的配对难题。 (Matrix pencils play an important role in numerical linear algebra. The problem of finding the eigenvalues of a pencil is called the generalized eigenvalue problem. The most popular algorithm for this task is the QZ algorithm, which is an implicit version of the QR algorithm to solve the associated eigenvalue problem B − 1Ax = λx without forming explicitly the matrix B − 1A (which could be impossible or ill-conditioned if B is singular or near-singular) )
