Question

Create a script that receives any row matrix with positive integer elements as the input (suppose you have at least two elements in your matrix), and creates the output as a row matrix with only two elements, where the first element will be sum of all the oddly placed element of the input, and the second value will represent the sum of all the evenly placed elements of the input: Example: A = [11 , 4 , 42 , 31 , 1] B=output = [54 , 35]

Answer 1

CODE :

%This function takes a row matrix as input. It calculates sum of

%even and odd positioned elements and returns them

%in a 1x2 matrix

function A = matrixOp(inputArray)

%create variables to store sum at even and odd positions

even_sum = 0;

odd_sum = 0;

for i = 1: length(inputArray) %loop through elements of input matrix    

   if (mod(i,2)== 0) %even position

       even_sum = even_sum + inputArray(i);

   else

       odd_sum = odd_sum + inputArray(i);

   end

end

   

%create answer array

A = [odd_sum, even_sum];     

end
