My solution is:
function out_str = cellstr_joiner(in_cell, delim)
y=in_cell;
y(find(cellfun(@isempty,cellfun(@strtrim,y,'UniformOutput',false))))=[];
out_str = strjoin(y);
out_str(find(out_str==' '))=delim;
end
On Matlab all tests pass but on the cody website the second test fail!

Test	Status	Code Input and Output
1	Pass	x = {'hello', 'basic', 'test', 'case'}; y_correct = 'hello basic test case'; assert(isequal(cellstr_joiner(x, ' '),y_correct))
2	Fail	x = {'this', 'one', '', 'has', ' ', 'some tricky', 'stuff'}; y_correct = 'this one has some tricky stuff'; assert(isequal(cellstr_joiner(x, ' '),y_correct)) Assertion failed.
3	Pass	x = {'delimiters', 'are', 'not', 'always', 'spaces'}; y_correct = 'delimiters?are?not?always?spaces'; assert(isequal(cellstr_joiner(x, '?'),y_correct))

Pass

x = {'hello', 'basic', 'test', 'case'}; y_correct = 'hello basic test case'; assert(isequal(cellstr_joiner(x, ' '),y_correct))

Fail

x = {'this', 'one', '', 'has', ' ', 'some tricky', 'stuff'}; y_correct = 'this one has some tricky stuff'; assert(isequal(cellstr_joiner(x, ' '),y_correct))

Assertion failed.

Pass

x = {'delimiters', 'are', 'not', 'always', 'spaces'}; y_correct = 'delimiters?are?not?always?spaces'; assert(isequal(cellstr_joiner(x, '?'),y_correct))
