说明：  数值计算课程实验的程序代码，很全面，很有用哦，希望能对大家有所帮助(Numerical experiment code program, very comprehensive and very useful Well, I hope you can help)

Compute the signal power

说明：  1．用Matlab产生正弦波,矩形波,以及白噪声信号，并显示各自时域波形图 2．进行FFT变换，显示各自频谱图，其中采样率，频率、数据长度自选 3．做出上述三种信号的均方根图谱,功率图谱,以及对数均方根图谱 4．用IFFT傅立叶反变换恢复信号，并显示恢复的正弦信号时域波形图 (1. Using Matlab generated sine wave, rectangular wave, as well as the white noise signal, and display their respective time-domain waveform of Figure 2. FFT to transform, showing their frequency spectrum, including sampling rate, frequency, data length of 3-on-demand. Made of the three signals in root-mean-square maps, power maps, as well as the number of root-mean-square map 4. Fourier Transform IFFT with the restoration of signals, and displays the sinusoidal signal the resumption of time-domain waveform)

matlab环境下的 PCA人脸识别方法，连续输入图像后，主成分分析，特征提取，形成特征脸训练测试，得出精度(face recognition)

主要介绍了新矩阵的创建，包括1）建立新矩阵；2）空矩阵；3）向量和子矩阵的生成；4）MATLAB中的特殊矩阵(Introduces a new matrix of creation, including 1) the establishment of a new matrix 2) empty matrix 3) vectors and matrices generated 4) MATLAB in the special matrix)

TFIND searches for one or more strings (boolean AND) in a text file. TFIND reports all lines where the string(s) were found (or NOT found by option). The search can be limited to a field in a fixed field (i.e. column oriented) list. An extended search mode is available, where only letters and digits are relevant. Other options: case sensitive search, alternative errorlevel with number of hits, header line with file name, LFN, custom prefix
