No.
You can use [num2cell(vector1),vector2] to get {[23] [54] [67] [987] 'test'}
or {vector1, vector2} to get {[23 54 67 987] 'test'}
both of those are cell arrays.
You can also use [sprintf('%d ', vector1), vector2] to get '23 54 67 987 test' which is a string.
All three have their use, but the first of those with num2cell is the one you probably want to use if you are trying to create values to write with excel, and the last of them with sprintf is the one you probably want to use if you are formatting a single line for display purposes. (If you are formatting multiple lines for display purposes then you will usually end up using the first version together with a "trick" for sprintf)
