四元数matlab代码中的IFFT程序，可以直接用的(Quaternion IFFT in matlab program code can be directly used)

指纹识别，已是现在科学最发达的技术之一，个人辛苦制作，毕业设计等必备(Fingerprint identification, is now one of science' s most advanced technology, personal hard production, graduation and other necessary)

给出了在卫星轨道确定中的各种测量量及测量噪声，敏感期的测量方程即转换矩阵(given in the satellite orbit determination of measurement and measurement noise, the sensitive phase of the measurement equation that the transformation matrix)

lle降维，可以参考非线性降维的方法，感觉没lda好用，比pca还行(LLE dimension reduction)

基于改进的PI模型对非线性曲线进行拟合，二次寻优算法进行参数辨识，用逆模型前馈补偿(Based on the improved PI model, the nonlinear curve is fitted, and the second optimization algorithm is used to identify the parameters, and the inverse model feedforward compensation is used.)
