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.
Var A UncA B UncB C UncC
'1' -0.0186917327837646 -0.0266242514128150 0.00420612704074986 -0.00200002085968102 0.107411895593770 0.0187751225715014

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

Thank you Greg. That has solved the problem now. I have the same no of cells in the output as in the original data set.

From the origical data (1 by 3071), I have the indices for both the empty and non-empty cells. is there any way that I can fill the newly generated cells array which is 1 by 2076 cell array (with empty cells removed ) with elements such as empty cells or NaN based on the indices in MATLAB where there were empty cells in the original data to keep the dimensions of the data same?
