I have a function that i want to return the first and last word from a string. so for example firstAndLast('matlab') should give me (m,b), however i am only able to get the first letter from this function?
function [first,last] = firstAndLast(instring)
first=instring(1);
last=instring(length(instring));
end

This is what your code does: I suspect that the problem is that were calling your function with only one output, instead of the two that it requires. In any case, in my answer I gave you a simpler way of doing this.
