How to calculate the number of values in a Gaussian distribution greater than one standard deviation?

I have produced a Gaussian Randon Variable ranging between -3 to 3. I want to calculate the number of values greater than one standard deviation. How may I do that?
pd = makedist('Normal')
x = -3:.1:3;
pdf_normal = pdf(pd,x);
plot(x,pdf_normal,'LineWidth',2)
length(x)
x = -3:.1:3;
y = pdf_normal;

Maybe you mean one standard deviation apart from the mean 0 of the standard normal distribution ?
Standard deviation of the standard normal distribution is 1. Thus there are
nnz(abs(-3:0.1:3) > 1)
values greater than one standard deviation apart from the mean 0 of the standard normal distribution.
