MATLAB: Replace missing value of cell array with NaN

missing

please find attached file, I tried to replace missing values (-1.27605887595352e+39) with NaN, unfortunately I encountering with the following error. Thanks in advance any help.
INDEX = cellfun(@(x) (x<-1),presglb,'UniformOutput',false) ;
>> presglb_new = presglb(INDEX);
Function 'subsindex' is not defined for values of class 'cell'.

Best Answer

ind  = cellfun(@(x) (x<-1),presglb,'UniformOutput',false);
for ii =1 :length(presglb)
    presglb{ii}(ind{ii}) = nan;
end
