Write a MATLAB user defined and Write a MATLAB program

• Write a MATLAB user defined function that takes as input a vector of values and returns the first five elements of the original array. Assume that the size of the input is more than five.
• Write a MATLAB program that inputs an array of integers and uses the previous function to find the largest value among the first five elements of the input array.

I expect your teacher wants you to do that, not us.

Please read this tutorial on how to submit an effective question here.

I couldn't do it so please help me and do it for me if you can.

Did you read that tutorial? Did you try to write anything? Attach what you tried here, and asking specific questions about where you are stuck.

If you have no idea how to even get started writing MATLAB code, then I recommend two steps:

• Watch the MATLAB Onramp
• Talk to your teacher, and tell them that you have no idea how to do this assignment

Trying to get other people to do your work is not the answer.

[per isakson]

The help on function() contains this as the first example.

Define a function in a file named average.m that accepts an input vector, calculates the average of the values, and returns a single result.

function ave = average(x)
    ave = sum(x(:))/numel(x); 
end

Isn't that close enough to your task to get you started? If not watch

I guess the statute of limitations has expired by now, so:

function out = get_first_five(A)
    out = A(1:5);
end

function out = get_largest_among_first_five(A)
    out = max(get_first_five(A));
end
