i have a cell_array with values

cellarr = {'b','a','a','a','b';0,'c',0,'b',[];0,'a',0,'d',0;'a','a','b',[],[]};

i wanted to delete the zeros in the cell_array so as to get the new cell array as below

shift the remaining columns to left after deleting the zero

new_cellarr = {'b','a','a','a','b';'c','b',[],[],[];'a','d',[],[],[];'a','a','b',[],[]};

sortlidx.m

Using the attached file sortlidx.m,

cellarr = {'b','a','a','a','b';0,'c',0,'b',[];0,'a',0,'d',0;'a','a','b',[],[]}
cellarr = 4×5 cell array
    {'b'}    {'a'}    {'a'}    {'a'       }    {'b'       }
    {[0]}    {'c'}    {[0]}    {'b'       }    {0×0 double}
    {[0]}    {'a'}    {[0]}    {'d'       }    {[       0]}
    {'a'}    {'a'}    {'b'}    {0×0 double}    {0×0 double}
map=cellfun(@isnumeric,cellarr);
cellarr(map)={[]};
[~,isort]=sortlidx(  ~map ,2,'descend');
cellarr = cellarr(isort)
cellarr = 4×5 cell array
    {'b'}    {'a'}    {'a'       }    {'a'       }    {'b'       }
    {'c'}    {'b'}    {0×0 double}    {0×0 double}    {0×0 double}
    {'a'}    {'d'}    {0×0 double}    {0×0 double}    {0×0 double}
    {'a'}    {'a'}    {'b'       }    {0×0 double}    {0×0 double}
