NANSTD same as STD but ignores NaN's. NANSTD is OBSOLETE; use NaN/STD instead. NANSTD is included to fix a bug in alternative implementations and to provide some compatibility. Y = nanstd(x, FLAG, [,DIM]) x data FLAG 0: [default] normalizes with (N-1), N = sample size FLAG 1: normalizes with N, N = sample size DIM dimension 1 sum of columns 2 sum of rows default or []: first DIMENSION with more than 1 element Y resulting standard deviation see also: SUM, SUMSKIPNAN, NANSUM, STD

- center CENTER removes the mean
- sumskipnan SUMSKIPNAN adds all non-NaN values.

- naninsttest NANINSTTEST checks whether the functions from NaN-toolbox have been
- nantest NANTEST checks several mathematical operations and a few
