这个函数提供灰度拉伸功能，输入图像应当是灰度图像，但如果提供的不是灰度图像的话，函数会自动将图像转化为灰度形式。x1，x2，y1，y2应当使用双精度类型存储，图像矩阵可以使用任何MATLAB支持的类型存储。(This function provides a gray scale stretching function of the input image should be grayscale image, but if not provided, then gray image, the function will automatically be converted to grayscale image form. x1, x2, y1, y2 should use double precision storage, image matrix can store any type of MATLAB support.)

利用 MATLAB 实现窗函数法设计 FIR 滤波器，主要是选择合适的窗函 数进行截断运算 (Window function method using MATLAB to design FIR filter, main is to choose the appropriate letter for window blocking operations.First theoretically to approximate the unit impulse response of ideal filter hd [k], to be determined by the passband and stopband attenuation index window function types, determined by transition zone FIR filter order M length (or N), and finally USES MATLAB to calculate the window function value, and hd wN [k] [k] value, so that the design of FIR filter h (k) MATLAB provides the blackman window function is: w = blackman (N) Where N is the length of the window function.)

用MATLAB读取obj格式的三维文件，实现了把obj读入matlab中并以点的形式储存，可以参考学习(Read obj format 3D files using MATLAB, obj read into matlab and to the point in the form of storage, you can refer to learning)
