If either, a symmetric matrix would stop being symmetric and would hence not be able to wear pants. With this conclusion in mind I propose that symmetric matrices are from now on called naked matrices instead.

Clearly would have one leg per column - joint at the top row

Why are we not considering the matrix as a whole, but as a fucking snake or something?

A matrix is already wearing chaps and needs no additional leg wear.

Wearable for infinite matrices

C vs Fortran

Both - one leg each way.

My matrices wear Hilbert Pants

That is a pant, not pants

It would wear it in the direction of the matrix determinant calculation, the right leg on the positive direction and the left leg on the negative
