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.)

The X, Y and Z matrix arguments can be used exactly as in the surf and mesh functions. But attention to the colors, because DXF fiels do not uses RGB palete. Instead they use a scaled color palete between 0 and 255.

说明：  In this paper, an attractive approach for teaching genetic algorithm has been presented. This approach is based primarily on using MATLAB in implementing the genetic operators: crossover, mutation, and selection. An advantage of using such an approach is that the student becomes familiar with some advanced features of MATLAB, and furthermore, with the availability of other MATLAB Toolboxes such as The Control Systems Toolbox, Neural Network Toolbox and Fuzzy Logic Toolbox, it is possible for the student to develop genetic algorithm-based approaches to designing intelligent systems, which could lead to his/ her final year or MSc project.

Matlab被称为第四代计算机语言，利用其丰富的函数资源，可使编程人员从繁琐的代码中解脱出来。Matlab用更直观、符合人们思维习惯的代码，代替了C和Fortran语言的冗长代码，给用户带来的是最直观、最简介的程序开发环境。(Matlab is called fourth-generation computer language function, programmers can be freed from the tedious code. Matlab with a more intuitive, the code in line with people' s habits of mind, instead of a lengthy code in C and Fortran languages, giving users the most intuitive and Introduction program development environment.)
