Don't know. All NCL's svd codes are direct interfaces to
LAPACK's 'subroutine dgesvd'. This does not support
missing values. Maybe set all values to 0.0
I am not sure how that would affect the results.

Please note the following
Newman and Sardeshmukh (1995) and Cherry (1996) urge caution when
interpreting results.
