How can I increment a vector by squaring?

I've been asked to write and display a vector" v = [1ˆ2, 3ˆ2, 5ˆ2, ..., (2n+1)ˆ2]". So how would I write the increment for that?

What have you done so far? What specific problems are you having with your code?

To square a vector element by element, you use .^2:

v = v .^ 2;

And constructing a v of [1,3,5,...] is trivial. Not sure what that has to do with incrementing a vector. Squaring is not incrementing by the normal definition of incrementing, where each element has the same number added to it, like v = v + increment.

If you have your vector already defined, you can use the dot operator to square each term individually. I.e.

x = [1 2 3 4];

x.^2

Will return the vector [1 4 9 16]. Is that what you are asking?
