extract file and the working is to get dct matrix of 256*256 image which is divide into each 8*8 image block

利用隐式QR方法求一个实矩阵全部特征值和特征向量的通用子程序。(use QR method is seeking a full matrix eigenvalue and eigenvectors of generic subroutine.)

利用matlab里面的吹风机数据，用前300个数据进行辨识。分别采用最小二乘辨识和相关性系数法辨识。并画出图形。通过对比最小二乘法和相关函数两种方法得出来的辨识图形。可知相关函数辨识的准确度更高。(Use a hair dryer inside matlab data before using 300 data identification. Were used to identify the least squares identification and correlation coefficient method. And draw graphics. By comparing the least squares method and related functions have two ways out of the identification graphics. Shows a higher correlation function identification accuracy.)
