本文详细介绍了16QAM调制方式的算法和理论(a good document for understand the theory and algorithm of 16QAM )

可以利用此书来编辑抗震问题的解决过程中利用matlab来实现(this is helpful to solve some problem which comes to anti-sesimic)

说明：  一种简单的灰度图片的匹配方法，是有自己编写(A simple gray scale image matching method is to prepare its own)

说明：  hallen equation :this equation is modeled as matrix equation (the voltage is equal two the current multiplied by resistance),the object is to find the current distribution.

irisData is 150x5. row: Sepal.Length Sepal.Width Petal.Length Petal.Width Group(1,2,or 3) the first 50x5 is Isis-setosa(1), the second 50x5 is Isis-versicolor(2), the last 50x5 is Isis-virginica(3). !!! Caution !!! X(50 + 21, :) equals X(50 + 50 + 27, :), but Y(50 + 50 + 21) DOESNOT equal Y(50 + 50 + 27)! So the algorithm will NEVER be 100 correct.

This algorithm solves the otimization problem min_x | y - A x |_2^2 + lambda Phi(x) and has applications in compressed sensing, image restoration and reconstruction, sparse regression, and several other problems.
