My code is
x =0:1:1000;
y=-((1/2).^x).*log2((1/2).^x);
H=sum(y);
And i want to plot (x,H),however,there is no curve in the figure when using plot(x,H),So i want to ask which command should i use?or if i can use the plot,where is my mistake?

When you do sum(y), it sums each element and gives you a scalar value. I think what you want is;
H = cumsum(y);
