Output of sprintf - string?
显示 更早的评论
Hi everyone,
on Matlab's documentation I read that sprintf is a function which takes as input data and returns a string. If I write:
x=sprintf('%d',2222)
the output has 1x4 dimension, thus is a character array and not a string (i use Matlab 2015). Why?
Thank you.

Because MATLAB only introduced the string class in R2016b, but previously any character array with size 1xN was called a "string". So for historic reasons there are many references to "strings" that are actually references to 1xN char arrays.
For example this includes the functions sprintf, cellstr, and iscellstr.
- Versions R2016a and before: The output is a 1xN char array.
- Versions R2016b and later: The output class is the same as that of the first input.
