针对水声中的矢量圆阵，比较MUSIC算法与MVDR算法的分辨率和抗各向同性噪声的能力。(For underwater acoustic vector in circular array, the MUSIC algorithm with the ability to compare MVDR algorithm isotropic resolution and anti-noise.)

本程序的基本功能是对信号进行傅里叶变换，并同时提取出他的时域和频域的特征值。(The basic function of this program is the signal to Fourier transform, and the simultaneous extraction of his time domain and frequency domain characteristic values.)

说明：  用matlab语言实现的将图像的进行dpcm编码算法，之后进行图像重构，进行前后图像的对比。(With matlab language will be dpcm image coding algorithm, after the image reconstruction, the images before and after contrast. )

幂法是一种计算矩阵主特征值(矩阵按模最大的特征值)及对应特征向量的迭代方法, 特别是用于大型稀疏矩阵。 (The power method is a method of calculating the matrix eigenvalue (matrix largest characteristic value) and the iterative method of the corresponding feature vector, particularly for large sparse matrix.)

2采用PCA对男女生样本数据中的身高，体重，喜欢数学，喜欢文学，喜欢运动，喜欢模式识别共6个特征进行特征提取（自己设定选取的特征个数），并基于所得到的特征采用SVM设计男女生分类器，并计算模型预测性能（包含SE,SP,ACC和AUC ）。(2 using PCA for boys and girls in the sample data height, weight, like math, like literature, like sports, like common pattern recognition feature extraction feature 6 (wherein the number of the selected set itself), based on the obtained feature using SVM classifier design boys and girls, and calculating prediction performance model (including SE, SP, ACC and AUC).)
