can someone help me get the MATLAB code

Let’s define two row vectors such that VecA = [3 4 5] and VecB = [5 12 13]. Compute the following:

1. dot(VecA,VecB)
2. VecA’ * VecB
3. VecA * VecB’
4. VecA .* VecB
5. VecA’ .* VecB
6. VecA .* VecB’

The operator, “ .* ” is called element-by-element multiplication (Gilat, Sec. 3.4) and the operator “ ’ ” is a transpose (Gilat, Sec. 2.4). Discuss which expression is identical to dot(VecA,VecB) and why not for other expressions.

You have the code. They are the lines after the '.' after the list-numbers.

If this is your question, then your first point along the way is the getting started section of the

matlab documentation, just put that string into a search and read-browse-and-test. That's the

best way to get into this. If you want to test-n-try your way forward, start up matlab, then define the first

array like this:

>> VecA = [3 4 5]

and so on...

...the help functionality of matlab is also good for initial browsing, most operations you will need have matlab-functions, so use help and lookfor to search for matlab-solutions already available.

Wellcome to matlab.
