In mathematics, the Fibonacci sequence is the following infinite sequence of natural numbers: The first element is 0, the second is 1 and each remaining element is the sum of the previous two: Each element of this sequence is called Fibonacci number. This sequence was described in Europe by Leonardo of Pisa, XIII century Italian mathematician known as Fibonacci. It has numerous applications in computer science, mathematics and game theory.

《MATLAB神经网络30个案例分析》中的第17个例子，案例17 SOM神经网络的数据分类--柴油机故障诊断。希望对大家有一定的帮助！(The MATLAB neural network analysis of 30 cases of example, 17 cases of 17 SOM neural network data classification, diesel engine fault diagnosis. Hope to have certain help to everybody! )

this is a matlab for the PSNR. In this .m I have been using the PSNR to evluate the quality of the audio quality. Its a very useful way to do it.

这是信号处理中循环谱密度的一个DEMO，有些文章中称其为循环平稳信号的组合切片(A demo of cyclic spectra density. it also can be called combinated splice on cyclostationary signal in some papers.)
