how do i get the cell matrix to be double ?

Hi all,

I have output a dict into a .txt file, and dict is in double format. Now I need to recapture back the data output from dict at .txt and to be name as Decompdict, however what I got is not in double format when I recaptured from .txt. May I ask how do I get a double format for my Decompdict? What I manage to get now is shown as below.

dict = 
        [-47]    [1x10 double]
        [-17]    [1x10 double]
        [ -7]    [1x9  double]
        [ -3]    [1x7  double]
        [ -2]    [1x4  double]
        [ -1]    [1x2  double]
        [  0]    [          1]
        [  1]    [1x3  double]
        [  2]    [1x5  double]
        [  3]    [1x6  double]
        [  7]    [1x9  double]
        [ 17]    [1x10 double]
        [ 30]    [1x10 double]

DecompDict = 
      '-47'    '[0,0,1,0,1,0,1,0,0,1]'
      '-17'    '[0,0,1,0,1,0,1,0,0,0]'
      '-7'     '[0,0,1,0,1,0,1,1,1]'  
      '-3'     '[0,0,1,0,1,0,0]'      
      '-2'     '[0,0,1,1]'            
      '-1'     '[0,1]'                
      '0'      '1'                    
      '1'      '[0,0,0]'              
      '2'      '[0,0,1,0,0]'          
      '3'      '[0,0,1,0,1,1]'        
      '7'      '[0,0,1,0,1,0,1,1,0]'  
      '17'     '[0,0,1,0,1,0,1,0,1,1]'
      '30'     '[0,0,1,0,1,0,1,0,1,0]'
