编制一个统计特定单词在文本串中出现的次数和位置的程序(The preparation of a statistical specific words in the text string appear in the number and location of the procedure)

Data files are in Matlab format. Each file contains fan and drive end vibration data as well as motor rotational speed. For all files, the following item in the variable name indicates: DE - drive end accelerometer data FE - fan end accelerometer data BA - base accelerometer data time - time series data RPM- rpm during testing

myfft是一个自编matlab函数，将输入的采样频率个采样点数建立一个数据库后，取出表中的数据进行fft分析，绘制出时频波形进行比较分析(myfft self Matlab is a function of the input sampling frequency of 000 sampling points after the establishment of a database and extract table data fft analysis, time-frequency mapping out a comparative analysis of waveforms)

说明：  多项式曲线拟合其中, x, y为已知数据点向量, 分别表示横,纵坐标, m为拟合多项式的次数, 结果返回m次拟合多项式系数, 从高次到低次存放在向量p中. (Polynomial curve fitting where, x, y as the vector of known data points, respectively, horizontal and vertical coordinates, m is the number of polynomial fitting, the results of m-fit polynomial coefficients returned from higher to Low times stored in the vector p,.)
