exp - Exponential

Syntax

Description

Y = exp(X) returns the exponential for each element of X. exp operates element-wise on arrays. For complex x + i * y, exp returns the complex exponential e^z = e^x(cos y + i sin y). Use expm for matrix exponentials.

Examples

Find the value of e^iπ:

y=exp(i*pi)

returns

y =

  -1.0000 + 0.0000i
