基于matlab的巴特沃斯低通滤波器设计程序(Matlab based on the Butterworth low-pass filter design program)

产生一个满足泊松分布的随机序列信号。用于通信系统的信源部分(have to meet a Poisson distribution of random sequence. Communication systems for the source of)

recursive least squares learning algorithm in fuzzy system

对于高程数据的处理，通常需要各种格式之间的转换，此程序是将usgs高程数据转为dem格式的数据。(For the treatment of elevation data, usually need to convert between various formats, this program is the USGS elevation data to DEM format data. )

Calc standard error of the mean or nonparametric

In theory, this algorithm tends to provide good generalization performance at extremely fast learning speed.(The experimental results based on a few artificial and real benchmark function approximation and classification problems including very large complex applications show that the new algorithm can produce good generalization performance in most cases and can learn thousands of times faster than conventional popular learning algorithms for feedforward neural networks)

it is a matlab program for ga sa tabu sworm opt heuristics we can also use matlab here. or there can

傅里叶变换后频谱图 B：陷波函数作用后的频谱图 C：经逆变换的滤波后图像，效果不是很理想 Ifft2：为验证自己的快速傅里叶变换程序的正确性，用matlab自带逆变换程序将频谱逆变换后图形，与原图相符，说明快速傅里叶变换程序正确。(This is a FFT )
