给出了30个matlab智能算法案例。对于智能算法的学习者有很大的帮助。(Gives 30 matlab intelligent algorithm cases. For intelligent algorithms learners a great help.)

包括：使用控制变量蒙特卡洛法和一般蒙特卡洛法的欧洲期权看涨价格程序；使用蒙特卡洛计算定积分；使用B-S公式计算期权价格。 ( Including: European call options price procedure using control variable Monte Carlo method and general Monte Carlo method using Monte Carlo calculation of definite integral use the B-S formula to calculate the price of option.)

自己编的闻邦椿书上的Riccati求转子临界转速，转子为单跨双转盘。有去除奇点，提取振型，收敛迭代为弦截法。有各向异性求取临界转速部分，不过结果可能不准确。(Riccati Wen Bangchun own series of books on demand critical speed rotor, the rotor is a single span double turntable. There are singular point removal, extraction modes, the convergence of iterations for the Secant method. Anisotropy strike critical speed section, but the results may be inaccurate.)

1 录入一段语音，对其进行时域频域处理，通过变频、变速达到变声目的，且使处理后的语音信号不影响正常收听与理解。 2 用图形用户界面（GUI）对上述变声前变声后进行时域频域图形输出，不同的频率、速度有不同的输出，且对前后波形进行比较 (1 entry a voice, the frequency domain and time domain by frequency conversion variable speed, processing to make the treatment and voice purpose, after the speech signal shall not affect the normal to listen to and understand. 2 with the graphical user interface (GUI) voice of the above voice before after the frequency domain in the time domain graphics output, different frequency, speed have different output, and compared before and after waveform )

说明：  一个完整的OFDM仿真程序，采用QPSK调制，有信道估计，大家交流下！(A complete OFDM simulation program, using QPSK modulation, a channel estimation, to share next!)

附录MATLAB 图像处理命令 1．applylut 功能： 在二进制图像中利用lookup 表进行边沿操作。 语法： A = applylut(BW,lut) 举例 lut = makelut( sum(x(:)) == 4 ,2) BW1 = imread( text.tif ) BW2 = applylut(BW1,lut) imshow(BW1) figure, imshow(BW2) 相关命令： makelut 2．bestblk 功 举例(Appendix MATLAB image processing an order. Applylut functions : the binary image using lookup tables for 2500 operations. Grammar : A = applylut (BW, lut) For lut makelut = (sum (x (:)) == 4. 2) = imread BW1 (text.tif) BW2 = applylut (BW1. lut) imshow (BW1) figure, imshow (BW2) related orders : makelut 2.
