Hello all,
So how do you delete all the rows that contain NaNs in a table (not a matrix or a cell array)? I have tried various versions of
tableA(~any(~isnan(tableA), 2),:)=[];
but none work.
Thank you

Make it easy for us to help you by suppling code to generate a table with nans in it. Then I can try some things. And do any of your columns contain anything other than numbers? Like strings or something?

If the table uses default missing values for the various types (see documentation for the various types; NaN is for numeric) then
tableA=tableA(~any(ismissing(tableA),2),:);
should do the trick. This will eliminate other variables that are missing besides numeric, too, of course, leaving only a complete table.

Hi,
I have tried this but got an error: Error using any Not enough input arguments.
I have first column as string and second is numeric with nan values sometimes inside. I want to get riw of those rows with nans.
thank you

Missing parens... ismissing(tableA) returns 2D logical, need any applied to it in 2d dimension to return the rows with missing value, then keep the complement.

If you have access to R2016b, you can use rmmissing .
