You're the only person who knows what a, b and c and R11 to R33 stand for.

So, the person who's best placed to answer this question is you. Just try it yourself.

of curse,

Why does the surface command not calculate the multiplication of matrices?

The syntax of Surface needs three separate expressions for x, y and z. You can't expect GG to think "whell the result of the product is a 3x1 matrix, so let's take the three elements of it as the three expressions." I'd say: Make the product yourself and define the expressions for x, y and z in the Surface Command with the Element Command.

if surface command calculate the multiplication of matrices 3d draw is very easy.

Lo que no es posible es usar una matriz de funciones como una función de R----->Rⁿ ⁿ (ojalá lo sea pronto)

yo uso matrices en surface() para hacer transformaciones lineales en otras superficies pero son matrices constantes

es evidente que sigues queriendo un giro negativo alrededor de un eje para crear superficies

ya comenté que no era dificil con las herramientas actuales como en el adjunto
