DR. Strang , thank you for another strong explanation of Distance Matrices and also the failure of the Triangle Inequality in Numerical Linear Algebra. Defining and explaining the Trace is another important part of Numerical linear Algebra.

Thank you sir, I understand the importance of checking triangular inequalities. By the way isn't the Distance Matrix 1st row [ 0 1 6], 2nd row [ 1 0 1] and 3rd row [6 1 0].

Is the distance matrix right?

It looks like dx2x3 is 6 when it should be 1, no? Right around 3:15
