% What is this?
s = 4;

% Now what?
v = 1:1:10;

% And, what is p?
p = 1./v;

% Does this make sense?
plot(s,s^2);

% Does this make sense?
plot(v,v.^2);

% What is this?
[2 3]/[4 5];

% What is this?
[2 3]./[4 5];

% What about 
[2]/[3];
[2]./[3];
2/[3];

% And?
3*v;
3.*v;

% Finally...
a = input('Enter number: ');
b = input('Enter a string: ','s');
fprintf('Answer is: %d %s\n',23,'No time to waste')

% Do you know how to save a file?

% Do you know why you want to do this?

% Can use the following to specify angles:
angle=0:2*pi/n:2*pi;

% Can also use 
angle = linspace(0,2*pi,n+1);

% For getting console input
n = input('Enter circle radius: ');
