FORMAT: Y = NANSUM(X,DIM)

  Sum of values ignoring NaNs
  This function enhances the functionality of NANSUM as distributed in
the MATLAB Statistics Toolbox and is meant as a replacement (hence the
identical name).
  NANSUM(X,DIM) calculates the mean along any dimension of the N-D array
X ignoring NaNs.  If DIM is omitted NANSUM averages along the first
non-singleton dimension of X.
  Similar replacements exist for NANMEAN, NANSTD, NANMEDIAN, NANMIN, and
NANMAX which are all part of the NaN-suite.
