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.
