Boolean to return true if the cell is empty/nan

Hi, I am trying to write a boolean variable that tells me whether the cell is not nan or nan, but I got an error that says "undefined function 'isnan' for input arguments of type 'cell'".

while (not(isnan(AU(row+1, col))))  % While the next row is available, skip this row. 
     row = row + 1;
end

The value in the bracket is true if the next row (row+1) is not nan.

Please help me fix this.

thank you !

It would be easier if we had your code to work with.

Try this:

~isnan(AU{row+1, col})

Address the cell elements using {}.
