normcdf

Cumulative distribution function for normal distribution

Usage

normcdf(x)

• It returns the CDF of the standard normal distribution evaluated at elements of x.

normcdf(x, mu)

• The input arrays x and mu should have the same sizes. Otherwise, one of them should be a scalar. They contain, respectively, means of the CDFs being evaluated, and x values at which the CDFs are evaluated.
• It assumes that the standard deviation is one.
• If x and mu have different sizes, one of them should be a scalar. The scalar input will be expanded to match the size of the other.

normcdf(x, mu, sigma)

• The input arrays x, mu, and sigma should have the same sizes. Otherwise, for any pair of input arguments having different sizes, one of them must be a scalar; the scalar input will be expanded to match the size of the other input.
• The inputs mu, sigma and x contain, respectively, means and standard deviations of the CDFs being evaluated, and x values at which the CDFs are evaluated.
• It returns NaN for negative elements of sigma.
