Structured condition numbers for a linear function of the solution of the generalized saddle point problem
Sk. Safique Ahmad, Pinki Khatun
This paper addresses structured normwise, mixed, and componentwise condition numbers (CNs) for a linear function of the solution to the generalized saddle point problem (GSPP). We…
