Question

Skyline matrix storage is in the form of ______

(a) Banded matrix

(b) Sparse matrix

(c) Singular matrix

(d) Identity matrix

The question was posed to me by my school principal while I was bunking the class.

My query is from Assembly of Global Stiffness Matrix for the Banded & Skyline Solutions in portion Trusses of Finite Element Method

Answer 1

The correct answer is (b) Sparse matrix

For explanation I would say: In scientific computing, skyline matrix storage or SKS or a variable banded matrix storage or envelope storage scheme is form of a sparse matrix storage format matrix that reduces the storage requirement of matrix more than banded storage.
