What is "alogarithm"? Is it a misspelling for "algorithm"?

As far as I understand, there is an error in the equation: F = − RB^TPx_k it should be replaced by: F = − RB^TP or does the feedback constant really depend on the state?

[edit] Links to Riccati equation

Could someone please write a page on the matrix Riccati equation, instead of simply linking to the Riccati differential equation. The connection between them isn't obvious. LachlanA (talk) 00:07, 22 January 2008 (UTC)
