Hi,
I have a 399×7 double array like this:
I wonder how it's possibe to create a new array with each row merged together to form an array like:
Thanks!

Try this: 
A = randi(99, 7, 4)
Amerged = str2num(sprintf([repmat('%d',1,size(A,2)) '\n'],A.'))
producing (in this run): 
A =
    53    60    11    40
    10    96    93    28
    41    43    19     4
    11    69    27    67
    12    76    79    43
    78    43    49    45
    29    65    77    61
    
Amerged =
    53601140
    10969328
     4143194
    11692767
    12767943
    78434945
    29657761
The str2double function is preferred for several reasons, however it will not work here to produce the result you want.
If you want ‘Amerged’ as a character array instead, omit the str2num call: 
    Amerged = sprintf([repmat('%d',1,size(A,2)) '\n'],A.')
It is necessary to transpose the matrix (here ‘A’) to get it tyo print correctly.
