There is a difference between string and char array since R2016b. Before that they could be used interchangeably, but now that is no longer true (although I believe some doc pages are still not careful about this).
The title and description have been updated, along with a few new test cases.
Wow this actually is such a great question
nice simple problem
Why this solution isn't correct? I tried this code on Matlab for pc and it's run correctly, but here on Matlab Cody's platform, it doesn't run. Someone can help me? Thanks
Look at the errors—your function never defines the output variable y.
Thank you for the help
We can simply use 'append'
function y = stringfirstandlast(x)
y = append(x(1),x(length(x)))
very easy like it!
Well, I guess my understanding that string is defined using (" " , i.e. double quotations) is incorrect. I thought class string was formally distinguished from char (defined using ' ', i.e. single quotes). I should have looked at the test-suite.
Yes, the title should be "Return the first and last character of a char array"
that is it
