Transform a_dW from primitive to characteristic variables.
On input, a_dW contains the increments of the primitive variables. On output, it contains the increments in the characteristic variables.
IMPORTANT NOTE: It is assumed that the characteristic analysis puts the smallest eigenvalue first, the largest eigenvalue last, and orders the characteristic variables accordingly.
