Question

1. In MATLAB on your computer (preferably) or on a workstation, Let x = [3456] a) Add 10 to each element ofx. Note that you can add a number to a matrix or vector b) Add 3 to odd-index elements ofx (keep using the original x [3 4 5 6] for each step) c) Compute the square of each element of x

Answer 1

Code

Given Vector

x=[3 4 5 6]

a) Addding 10 to each element of given x

p=x+10

b)Adding 3 to odd index elements of x

q=x;

q(1:2:end)=q(1:2:end)+3

c) Square of each element of x

r=x.^2

Result

x =

     3     4     5     6

p =

    13    14    15    16

q =

     6     4     8     6

r =

     9    16    25    36
