The matrix A consists of m rows and n columns. The matrix A is known as Sparse matrix if the:
  1. Atotal number of zero elements in the matrix A < m − n.
  2. Btotal number of zero elements in the matrix A > m*n.
  3. Ctotal number of zero elements in the matrix A > m*n/2.
  4. Dtotal number of zero elements in the matrix A < m + n.
Show answerHide answer

Correct answer: (C) total number of zero elements in the matrix A > m*n/2.

Explanation

A matrix is usually called sparse when most of its elements are zero, that is, when more than half of the m × n elements are zero.
