In a previous post, we discussed the confusion about the definition and associated properties of diagonally dominant matrices. In this blog, we answer the next question.

**What is a weak diagonally dominant matrix?**

The answer is simple – the definition of a weak(ly) diagonally dominant matrix is identical to that of a diagonally dominant matrix as the inequality used for the check is a weak inequality of greater than or equal to (≥). See the previous post on Clearing up the confusion about diagonally dominant matrices – Part 1 where we define a diagonally dominant matrix.
