描述铁电薄膜的存储窗口与铁电介电常数的关系(Describe the ferroelectric thin film ferroelectric memory window and the relationship between dielectric constant)

本文对倒立摆系统的Lagrange方程建模与模糊控制进行了简单介绍(In this paper, the inverted pendulum system Lagrange equation modeling and fuzzy control for a simple introduction)

本程序基于MATLAB编写，用于加密一幅彩色图像，通过将图像分解为RGB三通道，并且用颜色索引发完成图像的加密，程序中包含了解谜代码(The program based on MATLAB, is used to encrypt a color image, through the image is decomposed into RGB three-channel, and complete the image encryption with color hair, understand the enigma code were included in the program)

Matlab中没有现成的Hermite插值函数，必须编写一个M文件实现插值。 设n个节点的数据以数组x0 （已知点的横坐标）， y0（函数值）， y1（导数值）输入（注意Matlat的数组下标从1开始）， m个插值点以数组x 输入，输出数组y 为m 个插值。编写一个名为hermite.m的M文件。 (Matlab is not off-the-shelf Hermite interpolation function, we must realize the preparation of a document M interpolation. N nodes for the data to an array x0 (known point of abscissa), y0 (function value), y1 (numerical derivative) input (note the subscript Matlat array starting at 1), m to the array of interpolation points x input and output array y for m months interpolation. Hermite.m the preparation of a M-file.)

透视变换,由于摄像头存在透视效果 所以很多时候需要进行世界坐标系和图像坐标系下的转换(perspective transformation, As the camera lens effect so there is often the need for the world coordinate system and the image coordinate system conversion)
