How do I use single precision numbers in a summation? My result is not coming out as expected.

So this is the question I havve. However, when I change all the numeric values to single precision, it does not make a difference in the output. Any idea what I am doing wrong?

any suggestions would be appreciated!

You are not doing repeated addition. Repeated addition is not the same as multiplication.

Also, a and b are scalar, so a*b is a scalar, and there is no point in sum() of a scalar.

Hint: see repelem and repmat

ok, see I thought the sum thing was not correct, I was not sure how it should be done and someone else said to do it that way.

[Elaina]

It is expecting sum to be used, though. It expects a scalar result.

Another hint:

P*ones(1,Q)

is one way to construct a vector of size 1 x Q that contains all P

Ok, I had tried creating am array earlier but I obviously did not do it correctly. I used repmat and that fixed it. Thank you!
