Question

I have illustrated my question in the following images.

Data I require – ,

How do I convert 1×2 double into 1×1 string?

Thanks in advance

Answer 1

>> string(sprintf('[%d,%d]',s))
ans = 
    "[3,7]"
>> 

or, with features built into the new string class that mimic VB in many ways--

>> "["+s(1)+","+s(2)+"]"
ans = 
    "[3,7]"

I think the latter is more of a pain to write than the former, but to each his own...
