急求:AV+V(A的转置)+D=0, 求解V
AV+V(A的转置)+D=0A,V,D为矩阵.
求解V
各位高手请指教,如何求解此方程 能否说明一下A,V,D的阶数? 非常简单,你的是一个 非常简单,你说的是一个Lyapunov方程,用Matlab的函数lyap即可解决。该函数的使用如下:
LYAPSolve continuous-time Lyapunov equations.
X = LYAP(A,Q) solves the Lyapunov matrix equation:
A*X + X*A' + Q = 0
X = LYAP(A,B,C) solves the Sylvester equation:
A*X + X*B + C = 0
X = LYAP(A,Q,[],E) solves the generalized Lyapunov equation:
A*X*E' + E*X*A' + Q = 0 where Q is symmetric
多谢大家,特别是shenyongjun,非常感谢
