Hi,

I have ds containing cell arrrays (1 by 3571) and each cell index points to a table of 4 by 7 elements. When any cell is empty while concatenating, the above error is shown. Basically, I am trying to access the contents of the cells contained within the cell array "Table" and plot different fields on a 1 by 3571 grid where each index refers to a point on a lat/lon grid.

Here is the code: Any ideas how to fix the error and plot the content of the data set.

for n = 1:3571; 
    
    Unc{n}=Table{1,n}.UncA
end;
whos Table
  Name       Size                Bytes  Class    Attributes
  Table      1x3571            9326972  cell      

Here is the sample content of one of the cells contained in teh cell array.

If I'm understanding correctly, some indices of your cell array contain tables, and others are empty? What do you want to happen with the empty cells?

blnEmptyCells = cellfun(@isempty,Table);
%%% If throwing them out isn't ok, see additional posts below
Table(blnEmptyCells) = [];
Unc = cell(length(Table),1);
for ij = 1:length(Table)
    Unc{ij} = Table{1,ij}.UncA;
end
