exppdf

Probability density function for exponential distribution

Usages

exppdf(x)

• It returns the PDF of the standard exponential distribution evaluated at elements of x.
• x should be an array of non-negative real numbers.

exppdf(x, mu)

• The inputs x and mu should be arrays of non-negative real numbers. They should have compatible sizes.
• If the inputs have different but compatible sizes, one of them will be expanded to match the size of the other input.
• The inputs mu and x contain, respectively, the mean values and the $x$ values at which the PDFs are evaluated.
• If an element in mu is non-positive, the corresponding element in the output will be NaN.
