Replace Cell Array with other Cell Array

Hi, i want to replace cell array with other cell array's value. In example :

cell_array_1 = { 'i', 'love', 'you', 'you', 'love';
                 'i', 'you', 'love', 'i', 'much';
                 'i', 'love', 'you', 'so', 'much';
                 'i', 'love', 'you', 'so', 'much'}

cell_array_2 = {  [], [], [], 'so', 'much';
                  [], 'love', 'you', 'so', []}

Then i want to get below result :

 array_result = 

'i' 'love' 'you' 'so' 'much'
'i' 'love' 'you' 'so' 'much'
'i' 'love' 'you' 'so' 'much'
'i' 'love' 'you' 'so' 'much'

So, the first & second rows in cell_array_1 is replaced by cell_array_2. Is that possible?

Thanks in advance.

a1 = { 'i', 'love', 'you', 'you', 'love';
                'i', 'you', 'love', 'i', 'much'}
a2 = {  [], [], [], 'so', 'much';
                [], 'love', 'you', 'so', []}
idx=cellfun(@isempty,a2) 
a2(idx)=a1(idx)
