classical_music_2
MUSIC算法[1]是一种基于矩阵特征空间分解的方法。从几何角度讲，信号处理的观测空间可以分解为信号子空间和噪声子空间，显然这两个空间是正交的。信号子空间由阵列接收到的数据协方差矩阵中与信号对应的特征向量组成，噪声子空间则由协方差矩阵中所有最小特征值（噪声方差）对应的特征向量组成。(MUSIC algorithm [1] is a feature space based on matrix decomposition method. From the geometric point of view, the signal processing can be decomposed observation space the signal subspace and the noise subspace, it is clear that the two spaces are orthogonal. Signal Subspace data received by the array covariance matrix and eigenvectors corresponding to the signal component, the noise subspace from the covariance matrix of all the smallest eigenvalue (noise variance) eigenvector components.)

Mersenne-Twister
利用Mersenne Twister算法产生随机数，并测试和分析了其随机性。 程序中还加入了界面显示。
各个文件为：
initGenerator.m：
initGenerator函数，用于初始化随机序列的长度和值
generateNum.m:
generateNum函数，当index为0时被调用，用于创建624维的移位寄存器数组
extractNum.m:
extractNum函数，根据index当前值选择数组中的数生成随机数，同时改变index的值。
main.m:
main主函数，输入种子seed和产生数目total，输出产生结果及随机性测试结果
mymy.m和mymy.fig:
用于界面显示的部分，这两个文件会通过界面传入seed和total的值，并调用main函数，在相应的框中显示输出结果。
(According to the algorithm principle on Wikipedia, the Mersenne Twister algorithm to generate random numbers, and test and analysis of its randomness. The program has also joined the interface display.
The individual files are:
initGenerator.m:
initGenerator function used to initialize the random sequence length and value
generateNum.m:
generateNum function is invoked when the index is zero, and used to create a 624-dimensional shift register array
extractNum.m:
extractNum function, according to index the current value to select the number to generate random numbers, and change the value of the index in the array.
main.m:
main function of the input seed to seed and produce the number of total, the output generated results and the randomness of the test results
mymy.m and mymy.fig:
Part of these two files for interface display interface incoming seed and the total value of, and calls the main function, to display the output in the appropriate boxes.)

findEulerAngs
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)

Watermarking-using-3-level-SWT
Image water marking using Stationary Wavelet Transform with 3-level decomposition.
The problem with DWT is lack of shift-invarience and poor spatial resolution of the resultant image.
These were reduced with SWT, at the cost of memory requirements
