转载一个用MATLAB写的椭圆拟合的代码,有点用(Reproduced using MATLAB to write an ellipse fitting code, a bit used)

this program solves an Income Fluctuation Problem requires obj.m function which is the RHS of the Bellman equation as a function of c=consumption and x=cash in hand

短时傅立叶变换(STFT)源代码,用语非稳态信号的时频联合描述,可直接用于matlab程序之中.无解压密码.(short-time Fourier transform (STFT) source code, the language of non-stationary signals to the joint time-frequency description, Matlab can be used directly in procedures. No extract passwords.)

说明：  最小二乘法匹配，matlab代码，相关系数最大，单点最小二乘匹配(Least squares matching, matlab code, maximum correlation coefficient, single-point least squares matching)

MATLAB时频工具箱，比较完整，欢迎大家下载(Time-frequency MATLAB toolbox, relatively complete, welcome everyone to download)

在程序中用一般的MUSIC方法估计了信号的频谱，从两图中可看出在信号各频率处，频谱的峰值较大，故能明显的与噪声相区别，可在一定程度上避免在信号幅度较小时信号被噪声淹没的情况。(MUSIC method general procedures used to estimate the spectrum of the signal, it can be seen from the two graphs in the signal at each frequency of the spectrum peak larger, and it could be significantly distinguished from noise in the signal can be avoided to some extent a lesser extent, the signal is noise submerged.)

层次分析法（Analytic Hierarchy Process简称AHP）是将与决策总是有关的元素分解成目标、准则、方案等层次，在此基础之上进行定性和定量分析的决策方法。这里提出层次分析法的matlab源程序(AHP (Analytic Hierarchy Process referred AHP) is always associated with the decision-making elements into goals, guidelines, programs and other levels, on this basis for qualitative and quantitative analysis of decision-making methods. AHP presented here matlab source)
