How to find the saddle point of a matrix and how to locate it in columns and rows? A matrix is said to have a saddle point if some entry a[i][j] is the smallest value in the i'th row and the largest value in the j'th column. A matrix may have more than one saddle point....

A point where all the first partial derivatives of a function vanish but which is not a local maximum or minimum. For a matrix of real numbers, an element that is both the smallest element of its row and the largest element of its column, or vice versa. ...

On incremental approximate saddle-point computation in zero-sum matrix games The parameter robust controller design problem is often expressed as a game between the controller and uncertain parameters. The game is expressed as a con... Bopardikar,Shaunak,D.,... - AUTOMATICA -OXFORD- 被引量: ...
= x 3 show a saddle point in its domain. critical points of a function are the points in the domain of the function where either the first derivative of the function is equal to zero or the derivative does not exist. if x = c is a critical point for a function f and f(c) ...
We consider large scale sparse linear systems in saddle point form. A natural property of such indefinite 2-by-2 block systems is the positivity of the (1,... J Schöberl,W Zulehner - 《Siam Journal on Matrix Analysis & Applications》 被引量: 212发表: 2007年 Block triangular preconditio...
Case 2. Saddle point: λ1,2 real and opposite sign A saddle point occurs if λ1,2 are real and have opposite signs. Since one of the λ’s is positive, the system in the neighborhood of a saddle point is always unstable. Since the ratio λ2/λ1 is negative, Eq. 2.274 can be ...
