Bluetooth is a wireless technology that allows computers, phones, headsets, PDA s and other devices to wirelessly communicate over short distances (up to 33 feet). Bluetooth uses radio waves (in the 2.4 GHz range), and is designed to be a secure, low power and inexpensive way of connecting and exchanging information between devices without the need for wires or cables to link devices together.

说明：  基于频熵的改进减谱算法，程序中的r值，需根据实际情况更改大小！(Entropy-based frequency spectrum by improving the algorithm, the program of the r value, need to change the size of the actual situation!)

此篇文献是基于MATLAB的谱相减语音增强算法的研究，我写论文时给了我很大帮助，希望对大家也有用(This article will be based on MATLAB spectral subtraction speech enhancement algorithm, I wrote an essay gave me great help, we want to also be useful)

dw to xls 这个是用于pb9下的,已经修改过，不会弹出demo。 pb8的。 pb8设置有点麻烦，因为pb9是可以直接把(dw to xls)

用于计算相机外参数，即CCD像素坐标与三维世界坐标的对应关系，输入参数是世界坐标标定点对，输出外参数矩阵(Outside the parameters used to calculate the camera, that the correspondence between CCD pixel coordinates and the coordinates of the three-dimensional world, the world coordinate input parameter calibration point right, outside the parameters of the output matrix)
