Write a program which repeatedly reads numbers until the user enters "done". Once "done" is entered, print out the Max and Min. Use an array to store all the numbers. Example of execution:
Enter a number: 4
Enter a number: 5
Enter a number: 9
Enter a number: done
Max = 9, Min = 4

@Emma Swaggy: well, you made me laugh, which is a fine thing indeed.
Most of us here will not do other people's homework, but we are all happy to help you if you have specific questions about MATLAB, or are unsure how to approach solving a problem. In return you have to put in the effort yourself and show some initiative: for example MATLAB has very readable documentation which is easy to search using [your favorite internet search engine]. The documentation also includes working examples for almost every operation and function: the more you try yourself the more you will learn, the more you will understand, and the easier it will be for us to help you. We are not babysitters, nor a free tutor service, nor are we going to write all of your homework for you.
But please do ask us questions about how to use MATLAB.
You should start by doing the introductory tutorials (yes, really):

@EmmaSwaggy: next time you could search google :p it's really simple just find the keywords (For example here it's quite simple to spot out the keywords are min, max, input (like @KSSV said) ) then add "matlab" either the beginning or end :p

Code:
function[] = someonesHW()
idx=1;
prompt='Enter a number: ';
while true
inp=input(prompt,'s');
if (inp=="done")
break;
else
a=str2double(inp);
if isempty(a)
disp('Invalid input!');
continue
elseif isnumeric(a)==1
A(idx)=a;
idx=idx+1;
end
end
end
Min=min(A(:));
Max=max(A(:));
disp(['Max = ',num2str(Max),'; Min = ',num2str(Min)]);
end%someonesHW()
