Hail honourable svd experts, I'm using svdc and svsol to solve a matrix equation (like so). SVDC, A, W, U, V,/double result2 = SVSOL(U, W, V, data,/double) Is it a good idea to scale my data so that the A matrix is between a certain range? such as (0,1). I actually have julian day in there, so of course it seems wise to subract off a 'zero day' and bring the julian day into a normal range, but how important is it to scale the magnitude of the data? I figure I'd try a quick "ask the audience" before trying to figure it out. Thanks! Cheers, bob stockwell
