多项式同伦延拓的matlab工具箱以及练习程序 是以下书籍的matlab代码： Andrew J. Sommese and Charles W. Wampler, Numerical Solution of Systems of Polynomials Arising in Engineering and Science,World Scientific, 2005-Matlab programs to accompany the book: Andrew J. Sommes

matlab 应用数学工具箱的使用，包括概率统计、偏微分方程等。-matlab toolbox of applied mathematics, including probability and statistics, such as partial differential equations.

给出了x(n)=A*a^n*cos(w*n+theta),A，a，w，theta均为实数，程序中给出了如何不同过matlab的自带工具箱求解其DTFT的过程-Given x (n) = A* a ^ n* cos (w* n+ theta), A, a, w, theta, are real numbers, the procedure given how different matlab comes toolbox for solving itsthe process of DTFT

matlab源代码，是非负矩阵分解工具箱，包含乘法更新，最小二乘约束，投影梯度法等方法-Usage: [W,H] = nmf(X,K,alg,maxiter,speak) W: output matrix H: output matrix X: input matrix K: number of components alg: algorithm to use maxiter: maximum number of iterations speak: p
