¿Did you do your homework before posting? ¿Did you read the posting guide? I do not know of anything in R, but searching the web gives a lot of info, there is a good article in wikipedia, and there are a lot of papers accessible. Code, which probably can be used with R, can be found on the followin

[R] Lyapunov Discrete Time Equation

2010-01-29 Thread Giuseppe
Dear all, I need to solve the following Lyapunov Matrix equation: C=ACA' + B, with A and B given square symmetric matrices. Does anyone knows of a package that can solve the lyapunov matrix equation in R? Or even a C/Fortran implementation? I did not find one on netlib. Thank you. __
