Here's a technique that should work. Define x to be a structure with N
elements, and have x1 and x2 be tags of that structure. For example,

X = {X1: 0.0, X2: 0.0}
X = REPLICATE(X, N_ELEMENTS(X1))
X.X1 = X1
X.X2 = X2

Then, simply define the function being passed to SVDFIT such that it extracts
x1 and x2 from the structure array x.
