MATLAB: How to combine all columns of an array into one column

arrays

Suppose, If I have three elements in array A = [6, 5, 3] and I want
A = [653] as the only one element. How should I do this?
And I want general solution for this problem as my number of array elements may change but I want single array element.
Kindly help.
Thank you.

There's probably a more appropriate solution out there but the following should work fine:
A=[6 5 3]
str=num2str(A); %convert to string
str(isspace(str))=''; % remove spaces
A_new=str2num(str); % convert to number
