I need help with my homework, I am stumped on this question.
create a new function (Call it until) that takes as an argument an intefer n and spits out the vector x=(1,2,3,...,n)

I am not sure if that is what you are looking for. This function will display numbers from 1 to n. copy and paste this on a new M-file and save it with the name 'until'.
function [x]=until(n)
n=input('enter the number:'); x=[1:1:n]

Why are you ignoring the perfectly good value of n that is passed in as an argument?

@Meh: You really want to post an answer. Then I suggest "1:n" instead of "[1:1:n]".

Sean, are you including a trailing semi-colon for the anonymous function definition? And are you keeping to the requirement that the created function be named "until" and that it must take an argument and that argument must be named "n" ?
I get 13 only if I exclude the semi-colon.

@Sean de: I did not understand, that the function must be called "until". I called it "f" and counted the line break.

It's been a long time since I encountered a computer language with a "spit" operation, and I never did get to use it myself. I believe that in the early 1970's, one of the FORTRAN variant compilers produced at University of Waterloo had a SPIT command along with PRINT and PUNCH, intended for use with punching paper tape. There is, however, countervailing historical claim that the IBM computers that those versions of FORTRAN ran on, never had an accessible paper tape punch.
