Errors in using string and vector together

Hi I want to display string and vector of floating point numbers together, but matlab flags error - 'dimensions of matrices are not consistent'.

Here is code:

str = {'A ';'B ','C '};
arr=[1;2;3];
disp([str,arr]);

I want to display like this

A 1
B 2
C 3

Is there any alternative way? I am also interested to know how to create vector of string like

A
B
C

Any ideas? Thanks a lot!

disp only takes a single argument and have to dereference the cell array and combine into character string array. To be able to concatenate to the numeric array, have to convert them to string as well.

Looping and fprintf is often just as simple to handle each row at a time.

For the latter ?, Matlab doesn't care whether the inputs to colon are characters...

>> ['A':'C'].'
ans =
A
B
C
