this is a mass-spring system that solve the equation with initial values and show animated wave in gui

说明：  主要用于近红外光谱处理中光谱特征选择，是目前近红外光谱数据处理的重要方法之一。(Successive Projections Algorithm for NIR data analysis)

This code is a matlab neural network using the polynomial.

The p erceptro n algo rithm ceases to update the para meters only when all the training images ar e classified corr e ctly (no mistakes, no update s). So, if the training images are p ossible to clas sify co rrectly with a linear c la ss ifier, will the p erceptr on al gorithm find such a classifier? Yes , it does, and it w ill co nverge to such a classifier in a finite numb er of updates (mistakes ). We’ll sho w this in lectur e 2.

说明：  利用matlab的GUI功能编写的用于图像处理的代码。包括灰度化/对数指数变换/加噪声/平滑滤波/锐化/几何变换等。(Using the GUI function of MATLAB to write the code for image processing. Including graying / logarithmic exponential transformation / noise / smooth filtering / sharpening / geometric transformation, etc.)
