Question

MATLAB

Create a row vector vC=2:3:38 that has 13 elements. Then, create the following new vectors by assigning elements of vC to the new vectors: (a) A vector (name it vCodd) that contains all the elements with odd index of vC; i.e., vCodd = 2 8 14 ... 38. (b) A vector (name it vCeven) that contains all the elements with even index of vC; i.e., vCeven = 5 11 17 ... 35. In both parts use vectors of odd and even numbers to address the elements of vC that are assigned to vCodd, and vCeven, respectively. Do not enter the elements of the vectors explicitly.

Answer 1

clc;
clear all;
vC=2:3:38;
Neven=((length(vC)-1)/2);
Nodd=((length(vC))/2)+1;
n=1;
vCodd=zeros(1,Nodd);
for i=1:1:Nodd
vCodd(i)=vC(n);
n=n+2;
end

vCeven=zeros(1,6);
n=2;
for i=1:1:Neven
vCeven(i)=vC(n);
n=n+2;
end

disp('vC=')
disp(vC)
disp('vCodd=')
disp(vCodd)
disp('vCeven=')
disp(vCeven)
