实现了1999年huang等人提出的基本MNF算法，经验证可运行。-Huang et al 1999 MNF algorithm, proven run.

最小噪声分离，能够实现高光谱遥感图像的MNF正逆变换，进行图像降维与重建(Minimum noise separation can realize the MNF positive and inverse transformation of hyperspectral remote sensing images, and reduce the image dimension and reconstruct the image)

用于进行MNF变换，mnf用于对高维数据进行降维，特征提取(For MNF transformation, MNF is used for dimensionality reduction and feature extraction of high-dimensional data.)
