for loop to create a vector V of the squares

Use a for loop to create a vector V of the squares of the numbers -25 through 25.

I am looking for some help to get me started writing the code and help writing it itself. I am unsure of where to even start with this problem. Thanks in advance.

Because this is a very basic MATLAB question, and you don't even know how to start, I would recommending watching the MATLAB Onramp tutorial.

I have taken the onramp and fundamentals before. But I'm still confused about loops. Would I just start by making a vector of the squares?

It's a conundrum, because doing this calculation using a for loop is very "anti-MATLAB". "Making a vector of the squares" leaps right to the answer, and can be done in one line without a for loop -- and is actually the best way to do this.

But since your instructor is presumably trying to teach you about for loops ...

I suggest that you first decide on your algorithm, without writing any MATLAB code. Write down the list of steps. The first step might be "create an object with all the values from -25 to 25", for example. Then, convert those steps into MATLAB code.

So, would my code look like this:

result = [];

for i = -25:25

sum = i^2

result = [result sum];

end

Thanks so much for the help!
