I have a row vector with 7 numbers, e.g. 13 30 44 12 44 23 12. I want to join all these numbers into a single number, or 13304412442312. I have not been able to find a method to do this. Can anyone please suggest a method to do this without using a for loop.

x=[13 30 44 12 44 23 12];
stringX=num2str(x);
stringX=stringX(stringX~=' '); % remove the space
x2=str2num(stringX);

agreed , int64 is better.

Gives more dynamic range than double at cost of less flexible to other operations. Of course, OP will eventually run out of range there, too, if continues to increase the size of the vector...

a=[13 30 44 12 44 23 12]
b=strrep(num2str(a),' ','')
% This is a string, if you to get a number
b=str2num(strrep(num2str(a),' ',''))

ans =
