Question

Assume the vector AM contains an even number of elements. Develop a MATLAB script that asks the user for the vector AM and once the vector is found to contain an even number of elements, divide the product of its even elements by the sum of its odd elements without using the MATLAB functions prod or sum. Store the result in a variable called PDS. If AM is found to contain an odd number of elements, display an error message and prompt the user again for a vector with an even number of elements.

Answer 1

ANSWER:

the below is trhe copyable code with respect to the given data;

copyable code:

%myScript.m

%get the number of elements from the user.

nn=input("Enter the vector length:");

%check the element count

if(mod(nn,2)==1)

%if element count is not even then print error

error("number of elements is odd");

%end

end

%declare the vector AM

AM=zeros(nn,1);

fprintf("Enter the vector elements:\n");

%read the vector elements

for kk=1:nn

     AM(kk)=input("Enter the element:");

end

%create prodEven

prodEven=1;

%create variable sumOdd

sumOdd=0;

%use loop to find the even number product and odd number sum

for kk=1:nn

     %product of even number

     if(mod(AM(kk),2)==0)

          prodEven = prodEven * AM(kk);

     %sum of odd number

     else

          sumOdd= sumOdd + AM(kk);

     end

end

%define PDS

PDS =0;

%find the PDS

if(sumOdd>0)

     PDS = prodEven/sumOdd;

end

%display PDS

fprintf("The result is %f\n",PDS);
