Question

Solve in MATLAB

Problem 3: Given the vector x- [2 1 0 6 2 3 5 3 4 1 3 2 10 12 4 2 7 9 2 4 51 use a for loop to (a) Add up the values of all elements in x (b) Compute the cumulative sum, y, of elements in x You can check your results using the built-in functions sum and cumsum. Q.5 What is the value of the sum of elements in vector x? Q.6 What is the value of element y(16) in the cumulative sum vector?

Solution :

The matlab code to perform the required tasks is as follows,

clc;
clear;

x = [2 1 0 6 2 3 5 3 4 1 3 2 10 12 4 2 7 9 2 4 5];
sumX = 0;

for i = 1:length(x)
  
sumX = sumX + x(i);
y(i) = sumX;

end

disp(['Sum of X is) is : ',num2str(sumX)]);
disp(['Y(16) is : ',num2str(y(16))]);

And the results for Q.5 and Q.6 is,

Command Window Sum of X is) is: 87 Y(16) is 60 f>
