How to delete empty cells in a cell array?

I would like to delete all of the empty {0×0 double} cells in each row, then shift the cells that have values in them to the left.

Starting with:

    {["laterite-00001"]}    {[   30552]}    {[  227634]}    {[  123220]}
    {["laterite-00002"]}    {0×0 double}    {0×0 double}    {[1345]}
    {["laterite-00003"]}    {0×0 double}    {0×0 double}    {[443266]}
    {["laterite-00004"]}    {0×0 double}    {0×0 double}    {[87887]}
    {["laterite-00005"]}    {[1323]}    {[87455]}    {[23345]}
    {["laterite-00006"]}    {[43233]}    {[454547]}    {0×0 double}

I would like to end with this:

    {["laterite-00001"]}    {[30552]}    {[227634]}    {[123220]}
    {["laterite-00002"]}    {[1345]}
    {["laterite-00003"]}    {[443266]}
    {["laterite-00004"]}    {[87887]}
    {["laterite-00005"]}    {[1323]}      {[87455]}      {[23345]}   
    {["laterite-00006"]}    {[43233]}    {[454547]}

What you show us for input is a 6 x 4 cell array, some entries of which happen to contain empty arrays.

What you show us for desired output is something that does not exist in MATLAB: a rectangular cell array with "holes". Some people refer to this as a "ragged" array.

The closest you can get in MATLAB is that you could make a 6 x 1 cell array, each entry of which was a cell array:

{{"laterite-00001" 30552 227634 123220}
 {"laterite-00002" 1345}
 ...
}

arrayfun(@(IDX) {YourCell{IDX,:}}, (1:size(YourCell,1)).', 'uniform', 0)

Another alternative, which may not be what you are looking for:

>> c = {11 12 13; 21 [] 23; 31 [] []}
c =
  3×3 cell array
    {[11]}    {[      12]}    {[      13]}
    {[21]}    {0×0 double}    {[      23]}
    {[31]}    {[      32]}    {0×0 double}
>> for i = 1:size(c,1)
      j = ~cellfun('isempty',c(i,:));
       numNotEmpty = sum(j);
       cc = repmat({missing},1,size(c,2));
       cc(1,1:numNotEmpty) = c(i,j);
       c(i,:) = cc;
   end
>> c
c =
  3×3 cell array
    {[11]}    {[12]}    {[       13]}
    {[21]}    {[23]}    {1×1 missing}
    {[31]}    {[32]}    {1×1 missing}

Shifts the empty cell to the right, without any explicit loops:

c = {11,12,13;21,[],23;31,[],[]}
[~,idc] = sort(cellfun(@isempty,c),2)
s = size(c);
[idr,~] = ndgrid(1:s(1),1:s(2));
c = c(sub2ind(s,idr,idc))
