函数通过输入信号序列和函数序号，以及调制解调选择参数来完成扩频调制解调。original_seq是原始输入序列，可能是未调制序列，也可能是调制序列，walsh_num是walsh函数的序号，select选择对输入的序列进行调制还是解调。(function through the input signal sequence and function of the serial number and choice of modulation and demodulation parameters to complete spread spectrum modulation and demodulation. Original_seq is the original input sequence may not be modulated sequence, and may also be modulated sequence, walsh_num walsh function of the serial number, select choice of input sequence modulation or demodulation.)

利用谱减算法实现对航空录音的处理。主要思想是相对语音进行加噪声，然后再利用算法去噪声，比较前后信噪比的变化。根据实验结构，去噪效果明显。(The use of spectral subtraction algorithm for handling aviation record. The main idea is to increase the relative voice to the noise, and then use the algorithm to noise, signal to noise ratio before and after the change. According to the experimental structure, de-noising effect is obvious.)

该程序主要用来求解正弦分量的局部方差分维数，便于后续的模式识别方法的分类(The program is mainly used to solve the sinusoidal component of the partial differential side dimension, easy to follow the classification of the pattern recognition method)

3D方式演示欧拉角 通过鼠标就可以更改欧拉角的方位，其中代码适用于欧拉角方向余弦矩阵的转换。(findEulerAngs generates Euler angle sets and animates rotations in response to user manipulation of a 3D rigid body (a box). Use the mouse to change the orientation of the box. A wireframe of the original box position will appear. The Euler Axis button animates the rotation about the Euler Axis between the original and new box positions. The Rotate button calculates a set of Euler angles for the rotation type currently selected ( Body or Space ) and the axis set selected in the dropdown menu to orient the axes to the new box position. Derotate reverses this process and brings the axes back to their previous position. Once the axes have been rotated, subsequent rotations are calculated from this new orientation. This means that Space rotations use the coordinate system associated with the previous cube orientation (i.e. the axes of the wireframe cube). Axes DCM is the direction cosine matrix of the current axes orientation in the unrotated inertial frame. Box DCM (in)
