Matlab function that returns first and then last name

Hello everyone; I need to create a function as follows:

function lcf = lastCommaFirst(name)
where name is a two part name consisting of a first name, a space, and a last name. You may assume that there is only one space between the two parts of the name and no other spaces in name. The value returned by lastCommaFirst is a string consisting of the last name, followed by a comma and a space, followed by the first name.

This is the code that I was able to create so far but I don’t seem to be able to make it work:

==============================

function lcf = lastCommaFirst2(name)

first = string1;

last = string2;

if name == string1 && name == string2

lcf = disp(last && '  ' && first);

end

==============================

I would really appreciate it if you can help me with this code using simple explanations as I am just a beginner at matlab programming; thanks.

what are string 1 and string 2?

I was using them as values for (name) but that’s where matlab kept giving me errors, so I guess this is a mistake that I made in this code. I hope that this makes sense to you as I am just starting to learn about matlab programming.

one way

s = 'joe smith'
lcf = [s(find(isspace(s))+1:end) ',' s(1:find(isspace(s))-1)]
lcf =

smith,joe

Do not compare strings with == unless you are absolutely sure the both sides are exactly the same length. Instead, use strcmp() or isequal()
