将qq聊天记录导出为*.txt文本格式，然后再新建一个*.txt文本，使用字母或者数字重命名，再将导出的聊天记录复制、粘贴到新建的*.txt文本中。运行matlab,在命令窗口中输入文本名称，回车运行程序。 ">

对四分量的信号进行时频处理，得到小波尺度图、平滑伪wigner图、WVD图。有利于对信号进行很好的分析。(Four components of the signal time- frequency to give Scalogram, smoothed pseudo wigner diagram, WVD FIG. Conducive to good analysis of the signal.)

matlab基础教程，教你快速使用matlab软件和熟悉matlab语言。(matlab basic tutorial to teach you quickly matlab software and familiar matlab language.)

MATLAB平台下的CUDA加速库。运用该库可避免在MEX函数中来回拷贝GPU数据，提高MATLAB运行速率。附件给出一个简单的矩阵乘法的示例程序，该程序在GTX TITAN下运行效率比intel i7 3930k提高了10倍。(CUDA MATLAB platform acceleration libraries. Avoid the use of the library can be copied back and forth GPU MEX function data, improve MATLAB run rate. Annex gives an example of a simple matrix multiplication program that runs under the GTX TITAN 10 times more efficient than the intel i7 3930k.)
