Replace missing value of cell array with NaN

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'.

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

"ind" is corresponding to what?

is corresponding to the element below?

ind = cellfun(@(x) (x<-1),presglb,'UniformOutput',false) ;

Dear Bhaskar, after getting new presglb, you know how can I remove NaN?

Thanks

I know the following way, but the double size in the cell has changed, I want to keep the size as before.

>> result = cellfun(@(x) x(~isnan(x)), presglb, 'Uniform', 0);
