Deleting [ ] from a matrix

'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

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);

Thanks a lot Andrei

No, you are trying to create a cell array with a variable number of columns per row. That is not allowed.

The closest you would be able to get would be to change to a cell vector, one entry per row, each entry of which contained a cell vector, the entries of which were the strings. e.g.,

YourVector{3} = {'gene3' 'u' 'd'}
