Write a MATLAB code to obtain the following. Keep your code commented whenever required. Copy your source code and command widow outcomes and screen shots of any plots in your solution.

Generate the following vectors and also implement the Table-1 operations-map by employing the switch statement and an appropriate loop.

  • Generate a vector ‘DEC1’ as follow.

DEC1 =

5     1     3     0     2    5     0     2
  • Concatenate vector ‘DEC1’ eight times in order to obtain a bigger row vector ‘DEC’
  • N = The length of vector ‘DEC’
  • Generate a vector ‘t’ with ‘N’ equally spaced values within the range of 0 to 1
  • x = round of 26sin(2π9t).
  • y = ‘x’ multiply by 2.

Table-1

DEC(ind)

Operation

0

Res(ind)= x(ind) multiply by y(ind)

1

Res(ind)= x(ind) divided by y(ind)

2

Res(ind)= square root of [x(ind).y(ind)]

3

Res(ind)= x(ind) subtract from y(ind)

5

Res(ind)= x(ind) add to y(ind)

* In Table-1, ind is presenting the vector index.

Solutions

Expert Solution

The Matlab Code is as follows:

DEC1=[5 1 3 0 2 5 0 2]       % Generates the vector DEC1 with the given values
DEC = [DEC1 DEC1 DEC1 DEC1 DEC1 DEC1 DEC1 DEC1]   %Concatenate the 'DEC1' 8 times to obtain 'DEC'
N = length(DEC)   % Finding length of vector 'DEC'
t = 0:(1/N):1   %Generating vector t with 'N' equally spaced values within the range of 0 to 1
x = round(26*sin(2*pi*9*t))       % round off the result of 26sin(2pi9t)
y=x*2   % y = 'x'multiply by 2
%For loop for defining Table1 ind values 0 1 2 3 4 5
for ind=0:5
switch ind
   % the index of vector is positive in matlab
   case 0    % for ind = 0
       Res(ind+1)=x(ind+1)*y(ind+1)           % first element
   case 1   % for ind = 1              
       Res(ind+1)=x(ind+1)/y(ind+1)           % second element
   case 2   % for ind = 2              
       Res(ind+1)=sqrt(x(ind+1)*y(ind+1))       % third element
   case 3   % for ind = 3              
       Res(ind+1)=y(ind+1)-x(ind+1)            % fourth element
   case 5   % for ind = 5              
       Res(ind+1)=x(ind+1)+y(ind+1)           % sixth element
end
end
