说明：  Matlab智能算法30个案例分析，详细分析讲解了30个matlab案例(Analysis of 30 cases of Matlab intelligent algorithm)

Frequency Scale Conversion From f To f Scale frq2mel mel2frq mel The mel scale is based on the human perception of sinewave pitch. frq2erb erb2frq erb The erb scale is based on the equivalent rectangular bandwidths of the human ear. frq2midi midi2frq midi The midi standard specifies a numbering of semitones with middle C being 60. They can use the normal equal tempered scale or else the pythagorean scale of just intonation. They will in addition output note names in a character format.

Matlab function to implement the DFT equation: X = DFTsum(x) where x is an N point vector containing the values x(0),..., x (N − 1) and X is the corresponding DFT.

本程序基于约瑟夫森结的RSJ模型，对无微波辐照和微波辐照下约瑟夫森结的特性进行了数值计算求解，其中有微波辐照的RSJ模型求解采用了四阶龙格库塔方程函数，两种情况都给出了I-V特性曲线图（程序包中也附带），展现了量子化电压台阶。(This procedure based on the RSJ Josephson junction model, no microwave radiation and microwave radiation characteristics of Josephson junction has been calculated solving, in which microwave radiation has the RSJ model for solving a fourth-order Runge-Kutta equation function In either case, they are given IV characteristic curve chart (also included with the package), demonstrating the quantum level of voltage.)

实现了CA-CFAR算法仿真，得到其检测门限及检测概率曲线。并使用基于蒙特卡洛仿真方法得到检测门限及检测概率曲线，与传统的CA-CFAR算法进行了比较。(CA-CFAR algorithm to achieve the simulation, its detection threshold and detection probability curve. And use the resulting Based on Monte Carlo simulation method detection threshold and detection probability curve, with the traditional CA-CFAR algorithm were compared.)

Function analogous to DIFF, but takes sums instead.

改进神经网络PID程序用来位置跟踪，比普通的PID位置跟踪稳定性高(PID neural network program is used to improve location tracking, location tracking than conventional PID stability)

利用该代码可进行非线性光学材料的闭孔Z扫描曲线拟合，给出材料的三阶非线性光学极化率(theoretical to closed aperture Z scan)

A digital modulation using simulink. very useful for beginer
