第三次练习

教学要求：理解线性映射的思想，会用线性映射和特征值的思想方法解决诸如天气等实际问题。 3.1 对A????42?(0)(0)TT(x,x)?(1,2)，，求出{xn}的通项. ?12?13??程序：

A=sym('[4,2;1,3]'); [P,D]=eig(A) Q=inv(P) syms n; xn=P*(D.^n)*Q*[1;2] 结果： P =

[ 2, -1] [ 1, 1] D = [ 5, 0] [ 0, 2] Q =

[ 1/3, 1/3] [ -1/3, 2/3] xn =

2*5^n-2^n 5^n+2^n 3.2 B??0.40.2?1(0)(0)TT(x,x)?(1,2)对于练习1中的，，A???B12??10?0.10.3?求出{xn}的通项. 程序：

A=sym('[2/5,1/5;1/10,3/10]'); %没有sym下面的矩阵就会显示为小数 [P,D]=eig(A)
