Matlab矩阵运算函数-are函数（过时）

1、area函数：Riccati方程求解

2、用法说明

     Riccati方程的一般格式是：A'x+xA-xBx+C=0

     x=are(A,B,C) A、B、C为上述描述的Riccati方程的系数矩阵，x是方程的解

3、用法实例

>> A = [2 4 3;5 7 3;8 9 2]

A =

     2     4     3
     5     7     3
     8     9     2

>> B = [3 6 4;7 3 9;4 8 2]

B =

     3     6     4
     7     3     9
     4     8     2

>> C = [3 5 1;6 7 2;8 9 3]

C =

     3     5     1
     6     7     2
     8     9     3

>> x = are(A,B,C)
Undefined function 'are' for input arguments of type 'double'.
