MATLAB: Deleting [ ] from a matrix

Question

'gene1'     []     'u'  'u'     'd'         
'gene2'     'u'    'u'   []     'u'    
'gene3'     []    'u'  'd'     []     
'gene4'     'd'    'u'  'd'     'd'}

in this matrix [] must be deleted and output as

'gene1'     'u'   'u'     'd' 
        
'gene2'     'u'  'u'   'u'
    
'gene3'     'u'   'd'       
  
'gene4'     'd'   'u'   'd'     'd'

is it possible please help

Answer 1

d ={'gene1'     []     'u'  'u'     'd'       
'gene2'     'u'    'u'   []     'u'    
'gene3'     []    'u'  'd'     []     
'gene4'     'd'    'u'  'd'     'd'}
out = cellfun(@(x)x(~cellfun(@isempty,x)),num2cell(d,2),'un',0);
