I have a 54x8 cell array that contains only strings. Most of these strings represent numbers and I would like to detect which cells are NaN.
One possibility would simply be to replace all NaN with ' ' or to check whether each d{i,j} == NaN.
Thanks

cellfun(@(C) any(isnan(C(:)), YourCell)
However in your situation you could probably go with
cellfun(@isnumeric, C)
Oh wait, when you say NaN, do you mean the string 'NaN' ? If so then
cellfun(@(C) strcmp(C, 'NaN'), C)

G H are you comparing numeric nan or string 'NaN'

Hello,
@WalterRoberson:
Is there a way to use this
cellfun(@(ds) strcmp(ds, 'NaN'), ds))
when the cell elements are not aligned but below each other?
Thank you!
