 \item \emph{log10 (array) }: Returns the base 10 logarithm of an array of scalars/vectors/tensors.
 
+\item \emph{make\_point\_mask\_from\_NaNs(dataset, array)}: This function will create a ghost array corresponding to an input with NaN values. For each NaN value, the output array will have a corresponding value of vtk.vtkDataSetAttributes.HIDDENPOINT. These values are also combined with any ghost values that the dataset may have.

+\item \emph{make\_cell\_mask\_from\_NaNs(dataset, array)}: This function will create a ghost array corresponding to an input with NaN values. For each NaN value, the output array will have a corresponding value of vtk.vtkDataSetAttributes.HIDDENCELL. These values are also combined with any ghost values that the dataset may have.
+
 \item \emph{max (array)}: Returns the maximum value of the array as a single value. Note that this function returns the maximum within a block for AMR and multi-block datasets, not across blocks/grids. Also, this returns the maximum within each process when running in parallel.
 
 \item \emph{max\_angle (dataset) }: Returns the maximum angle of each cell in a dataset.
