IsZeroMatrix

Tests if a matrix is a zero matrix.

Syntax

• IsZeroMatrix(A[, ε])

  • A is a matrix

  • ε is a positive number

Description

If A is a matrix, then IsZeroMatrix(A, ε) returns true iff A is a zero matrix, that is, iff all its entries are 0 (compared with epsilon ε).

For all matrices A, IsZeroMatrix(A, ε) = IsZero(A, ε).
