I need to concatenate the elements of firstname until it contains the whole first name(nate) of myname.
myname = 'Nate Johnson';
firstname = '';
length(myname)
f = strcat(myname, g);
while length(myname) < 7
firstname = myname;
x = myname;
end
disp(x)

while length(myname) < 7
firstname = myname;
x = myname;
end
Inside your loop, you are not changing myname, so if your loop starts going at all, your loop will never end.

presuming the next step would be to also isolate lastname.
Or, alternatively
>> firstname=extractBefore(myname,' ')
firstname =
'Nate'
