W1Q1: Create a sequence of numbers

Description ----------------------------------------------------------

*Generate a sequence of numbers _between 2 and 22, spaced 2
 apart_. You can use a* |colon| *operator, or you can use a
 pre-programmed function such as* |linspace|. *The variable that you
 create must be called* _y_ .

You may or may not close with a semicolon, to suppress output to your
screen. There are, literally, an infinite number of ways in which you
can accomplish what's asked. You may choose to use brackets or not in
this example. In the template, I have written square brackets within
which you will type your solution.

Your _script_, the answer to this question, is only that one line
long! And you will only type within the brackets.


Solution Template ----------------------------------------------------

y=[];


Reference Solution ---------------------------------------------------

switch randi(3)
    case 1
    y=2:2:22;
    case 2
    y=linspace(2,22,11);
    case 3
    y=[2:2:22]';
end


Visible Tests --------------------------------------------------------



Hidden Tests ---------------------------------------------------------

run('solution');
x=[2:2:22]';
assert(isequal(x,y(:)));



W1Q2: Find a specific entry in a vector

Description ----------------------------------------------------------

*A vector is an array of numbers. The template is making a vector for
 you, the variable named* |v| . *Assign the* _fifth_ *element of the
 vector* |v| *to a* _new_ *variable, named* _p_.


Solution Template ----------------------------------------------------

% Here I am making a very specific vector for you.
v=[1 exp(1) pi 99.9 -4 5 1e6];
% On the next line, extract the fifth element of v and assign it to p


Reference Solution ---------------------------------------------------

p=v(5);


Visible Tests --------------------------------------------------------

run('solution');
assert(logical(exist('p','var')));


Hidden Tests ---------------------------------------------------------

run('solution');
assert(isequal(p,-4));
