说明：  一个非常不错的PCR工具包 功能比较齐全包含有PCRCV 等 并有帮助说明(A very nice feature relatively complete PCR kit and help explain)

水声声速剖面反演的MATLAB仿真。用了比较基本的滤波方法ENKF。(Water sound velocity inversion sectional MATLAB simulation. With a relatively basic filtering method ENKF.)

说明：  MATLAB的空间决策支持系统 MATLAB的空间决策支持系统(MATLAB MATLAB spatial decision support system for spatial decision support system)

PCA主成分分析的matlab代码，可以用来学习原理，效果还不错(PCA principal component analysis can be used to study the principle, the results were pretty good)

matlab下m文件，能够提取compass三轴原始数据，并自动进行拟合矫正，得到其变换矩阵。将椭圆自动校正为圆心在原点的正圆。专门用于磁力计和重力计的自动校正。(m file matlab compass can be extracted under triaxial raw data and automatically correct fitting to give its transformation matrix. The ellipse is automatically corrected to a perfect circle centered at the origin. Specifically for magnetometer and gravity meter automatically corrected.)
