包含三个M文件，程序为本人自行编译完成，Demo中设有仿真信号验证，并经本人实际齿轮箱信号（轴承外圈故障）测试，经包络分析结果显示能够有效定位轴承外圈故障频率。
亲测可用。(It contains three M files. The program is compiled and completed by myself. Demo has simulation signal validation. It has been tested by my actual gear box signal (bearing outer ring fault). The envelope analysis results show that it can effectively locate the bearing outer ring fault frequency.

The pro-test is available.)
