Hi guys.

Do you know if there is a difference between these two ways of defining a vector?

real NV_VEC(vector)

real vector(ND_ND)

NV_VEC(psi) is used to declare a vector as it follows:

real NV_VEC(psi);
NV_D(psi, =, F_U(f,t), F_V(f,t), F_W(f,t));

While the vector(ND_ND) is used to declare matrix (2x2 and 3x3) for 2D and 3D, for example

real A[ND_ND][ND_ND]

for (i=0; i<ND_ND; ++i)
for (j=0; j<ND_ND; ++j)
A[i][j] = f(i, j);

not sure I made myself clear.
