几种优化算法

有一学生成绩管理数据库如下表，要求建立一SAS数据集score，并输出显示 创建一个新的数据集class，新增平均成绩aver变量和等级考评grade变量，grade的值是根据aver值的大小给出A、B、C、D四个等级，并显示新数据集class(A student achievement management database as the table, called for the establishment of a SAS data set score, and output display create a new data set class, add an average score aver evaluation variables and grade level variables, grade values are based on the size of a aver value the A, B, C, D four grades, and displays the new data set of class)

基于自建数据库的音乐识别及检索软件 ； 利用Matlab开发软件, 通过抓取录入歌曲的音高(pitch tracking)绘出声音的频率变化并进行降噪和润滑（smoothing）处理 与数据库中歌曲的频率变化图比对，计算出相似度top10的歌曲并显示。 (Based on self-built of music recognition and retrieval software developed using Matlab software, change the pitch of a song by crawling entry (pitch tracking) plots the frequency of the sound and noise reduction and lubrication (smoothing) processing Frequency changes in the diagram songs than calculate the similarity top10 songs and displayed.)

BCH(15,5,7)a communication system consists of binary source, 3 error-correcting BCH code of length 15 over GF(24) (i.e, BCH (15,5,7 code), the primitive polynomial is p(x)=1+x+x4), BPSK modulator, AWGN channel, coherent demodulator, decoder (either BMA or EA could be utilized to solve the error locator polynomial) and sink. Simulate and draw its error performance with and without BCH coding, together with the theoretical no-coding curve, i.e. two BER-EbNo curves.(a communication system consists of binary source, 3 error-correcting BCH code of length 15 over GF(24) (i.e, BCH (15,5,7 code), the primitive polynomial is p(x)=1+x+x4), BPSK modulator, AWGN channel, coherent demodulator, decoder (either BMA or EA could be utilized to solve the error locator polynomial) and sink.
