  %RMMISSING  Drop missing values (MATLAB R2016b+).
  %
  %  An owuitools compatibility shim; see contains.m for the policy.
  %
  %  Numeric and logical data only, where "missing" means NaN. MATLAB also
  %  accepts tables, categoricals, strings and datetimes, where missing
  %  means something different in each; none of those types exist here, so
  %  this refuses them rather than inventing an answer. For a vector the
  %  missing elements go; for a matrix the whole ROW goes, as in MATLAB.
