MATLAB: Summation of 2 separate matrix

summation

hi can anyone help me out with this problem i am having

x=[1 2 3 4 5];
y=[5 23 44 14];

i want to find the summation of x*y^2 so i am using loop function but my result come as 1

i=0;
for i=i+1
    i<5;
    d=0;
    c=sum(x(i)*y(i)^2);
    d=d+c;
end
>> d=.

can anyone please correct me where i am making mistake

thank you

x=[1 2 3 4 ];
y=[5 23 44 14];
out=sum(x.*y.^2)

x=[1 2 3 4]
y=[5 6 7 8]
n=length(x)
for i=1:n
  z(i,:)=x(i).*y
end

You want to use bar()

    x = 1:5;
    y = [5 3 2 6 1];
    bar(x,y)
