Diagonally Dominant Matrices - Invertible at a Glance! | Linear Algebra

We introduce diagonally dominant matrices and prove that a diagonally dominant matrix is invertible. We'll see examples of diagonally dominant matrixes that are necessarily invertible, a not diagonally dominant matrix which is still invertible, and a noninvertible matrix which is not diagonally dominant. #linearalgebra

Very clear articulation. Goes a long way hearing confidence in your voice.
Much better than my current professor.

That's really cool; I've never come across the concept of diagonal dominance before! Well, either that or I forgot...

Thanks for your videos. They are always much more clear than my professors 😊😅
