Agreed. As a matter of fact the simplest convolutions of
tensors are out of date. It is like there's no need to
calculate inverse matrix. Mir is the usefull work for author,
of course, and practically almost not used. Every one who
needs something fast in his own tasks should make same things
again in D.
"no need to calculate inverse matrix" What? Since when?
I dont know what he meant in this context, but a common
technique in computer graphics is to build the inverse as as
you apply computations.
It makes sense for simplest cases if matrices are small (2x2, 3x3
or even 4x4) and you have to multiply them at least thousands of
times.
