Write a function largest () such that it can accept multiple numbers and return the largest item from the given list.

Write a function largest () such that it can accept multiple numbers and return the largest item from the given list.

This sounds like a homework assignment. If it is, show us the code you've written to try to solve the problem and ask a specific question about where you're having difficulty and we may be able to provide some guidance.

If you aren't sure where to start because you're not familiar with how to write MATLAB code, I suggest you start with the free MATLAB Onramp tutorial to quickly learn the essentials of MATLAB.

If you aren't sure where to start because you're not familiar with the mathematics you'll need to solve the problem, I recommend asking your professor and/or teaching assistant for help.

I JUST DONT KNOW HOW TO GET MULTIPLE INPUTS

[dpb]

See syntax @<@doc:function> shows how...although none of the examples use more than one, the syntax is shown in general.

To be really neat and (probably) get extra credit, you might look at @<nargin> and @<varargin> as well...

Just dive in...

There is already a MATLAB function that "can accept multiple numbers and return the largest one"

x = [2,15,23.7,91.4,80.3] % vector with multiple numbers

x = 1×5

2.0000 15.0000 23.7000 91.4000 80.3000

xmax = max(x) % return the largest one

xmax = 91.4000

[Jon]

if you need to promt the user for the list then you can do something like this:

x = input('enter list of numbers, for example [1.1,2.3,38.7,5.3] ')

Most homework assignments (as this must surely be) preclude the use of builtin functions to solve the problem as the pegagical exercise for the student...and, it's not clear the intent of this exercise is to consider a vector of multiple values as "multiple inputs" or not -- my reading is "not", but it doesn't say so unequivocally, granted.
