MATLAB: Struct contents reference from a non-struct array object

Question

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.

Answer 1

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
