I get Subscript indices must either be real positive integers or logicals.

if true
% N = 5000;
z = 2*randn(N,1);
x = (-9:0.25:9);
z1 = reshape(z,[10,500]);
y = mean(z1);
sdy = std(y);
E = exp(-(x.^2)./(2*(sdy^2)));
DeltaNy = (500./(sdy*sqrt(2*pi))).*E.*0.25;
plot(x,DeltaNy,'r-');
end
I have to use the formula for delta n which depends on the standard deviation of y but this values is too small and
I get Subscript indices must either be real positive integers or logicals. I don't know how to make the formula work, I need it to plot the normal distribution on a histogram. I have to use THAT formula and cant change it.

The code you posted runs without error for me (in R2017b).
If it is throwing an error, please copy the complete error message (all the red text) from your Command Window and paste it to a Comment here.

When k is 1, then k-5 is -4. You can't have a negative 4 as the row number of a matrix.
