(a) Column height

(b) Row height

(c) Matrix height

(d) Undefined

I have been asked this question in unit test.

The doubt is from Assembly of Global Stiffness Matrix for the Banded & Skyline Solutions in division Trusses of Finite Element Method

Answer 1

Right answer is (a) Column height

Explanation: Skyline assembly matrix scheme of form of a sparse matrix that reduces the storage requirement of a matrix than banded approach. The first step of skyline assembly involves the evaluation of the skyline height or the column height for each diagonal location.
