用matlab实现Romberg积分，该算法简单易懂，容易初学者掌握(Romberg Integral using matlab，easy to understand)

MatLab Engineering Mathematics about Mathematics and application

说明：  matlab 闭曲线B样条的拟合，算例可直接使用，使用时只需要修改nq文件或者aline文件中的u1即可，也可定义u1后直接run aline(matlab closed B-spline curve fitting, numerical example can be used directly, using only a need to amend the nq documents or document aline can u1, u1 can be defined also directly run aline)

对原始灰度图像进行图像压缩，对此图进行 8×8 DCT 变换后，分别只保留 DC系数，以及保留前 4、8、16 个变换系数(DC＋AC) ，然后再分别进行 IDCT 变换 (The original gray image compression, this map for 8 × 8 DCT transform, respectively, to retain only the DC coefficient, and to retain the former 4,8,16 months transform coefficients (DC+ AC), and then separately IDCT transform)

用Matlab绘制心形图形的程序，图形很漂亮哦(Matlab draw heart-shaped graphics program, graphics is very beautiful, oh )

这是周建兴编写的《matlab从入门到精通》第三章的所有源代码，都可以运行的出来，和课本上的一样，(This is Zhoujian Xing written 《matlab从入门到精通》第4章的所有源代码，都可以运行的出来，和课本上的一样，)

谱聚类算法的matlab实现谱聚类算法的matlab实现(spectral clustering algorithm matlab)

FFT算法C语言实现 和MATLAB中fft函数结果一样的功能(FFT algorithm C language and MATLAB fft function results in the same function)
