finding the 10 biggest values in a cell array

I have a cell array 10x10 that consists of of several matrices (1000x1) with integers. I want to find the 10 biggest integers in that cell array and the corresponding column and rows in the cell array and the corresponding row in the matrix.
thanks

Use cell2mat and find would be the easiest way. If you do not want to convert the cell array into the double array, use cellfun .
data_matrix = horzcat(YourCellArray{:});
[sorted_matrix, sort_idx] = sort(data_matrix, 'descend');
best_10_vals = sorted_matrix(1:10);
best_10_idx = sort_idx(1:10);
[orig_row_in_cell, cellnum] = ind2sub(size(data_matrix), best_10_idx);
[orig_cell_row, orig_cell_col] = ind2sub(size(YourCellArray), cellnum);
Now,
YourCellMatrix{orig_cell_row{K}, orig_cell_col{K})(orig_row_in_cell(K)) == best_10_vals(K)
