快速傅里叶变换的matlab实现，用于对信号进行频谱分析(Fast Fourier transform matlab implementation for spectral analysis of signals)

matlab中的命令集合，准确的使用matlab命令操作(the matlab command collection accurate use matlab command operation)

For using this code need to use signal toolbox and general toolbox in your matlab Inpainting using sparse regularization. Consider the pepper image with many missing pixels. Assume that the image is noisy-free. (a) Inpaint the image by using orthogonal wavelet sparsity. (b) Inpaint the image by using a different sparsity prior. Based on the outputs, it is clear that the inpainting result obtain by Sobolev is much better than other methods (i.e. Orthogonal wavelet sparsity and Invariant wavelet sparsity).

经验模态分解，matlab实现，用于信号的降噪处理，提取特征值处理等经验模态分解，这是用汉语注释的EMD程序，很不错的。％ 语法 ％ IMF = EMD(X) ％ IMF = EMD(X,..., Option_name ,Option_value,...) ％ IMF = EMD(X,OPTS) ％ [IMF,ORT,NB_ITERATIONS] = EMD(...) (This is annotated in Chinese EMD procedures, very good. Syntax IMF = EMD (X) IMF = EMD (X ,..., Option_name, Option_value ,...) IMF = EMD (X, OPTS) [IMF, ORT, NB_ITERATIONS] = EMD (.. .(Empirical mode decomposition, matlab, used in signal noise reduction processing, extraction of characteristic value processing, etc)

ni5641r模拟输入代码，并画功率谱估计。(ni5641r analog input,and draw power spectrum estimation.)

这个函数估计到库默尔与第N系列的广义超几何微分方程解的权力。库默尔的差分方程为： x *的克 （十）+（二- X）的*克 （​ ​ x）的- A *的为g（x）= 0 该代码只有4线长，利用Matlab的向量运算有权采取了第N广义超几何级数的权力的总和。(This function estimates the solution to kummer s differential equation with the first N powers of the generalized hypergeometric series. Kummer s differential equation is given by: x*g (x)+ (b- x)*g (x)- a*g(x) = 0 The code is just 4 lines long, using the power of Matlab s vector operations to take the sum over the first N powers of the generalized hypergeometric series.)

分数阶傅里叶变换对chirp信号进行解调，同时对比匹配滤波器的解调性能(Fractional Fourier transform of the chirp signal is demodulated, and the demodulation performance comparison of the matched filter)

Jacobi矩阵一般是坐标变换时用的——这个坐标系的坐标依次对那个坐标系的坐标求偏导数即得Jacobi矩阵。积分时从直角坐标变到球坐标、极坐标肯定要在积分号里乘上Jacobi矩阵的行列式。 若其特征值全为正，则此Jacobi矩阵正定，即它的任何二次型都大于零。并且如果是对称Jacobi矩阵，还可以实相合于一个单位阵。是比较强的条件。矩阵A的特征值是这个关于x的方程的所有根 det(A-xI)=0(Jacobi)
