Syntax

Y = exp(X)

Description

example

Y= exp(X)returns the exponentialexfor each element in arrayX. For complex elementsz=x+iy, it returns the complex exponential

e z = e x ( cos y + i sin y ) .

Useexpmto compute a matrix exponential.

Calculate the exponential of 1, which is Euler's number,e.

exp(1)
ans = 2.7183
Open Live Script

Euler's identity is the equality e i π + 1 = 0 .

Compute the value of e i π .

Y = exp(1i*pi)
Y = -1.0000 + 0.0000i
Open Live Script

Plot y = e x / 2 forxvalues in the range [ - 2 , 1 0 ] .

X = -2:0.5:10; Y = exp(X/2); plot(X,Y)

Figure contains an axes object. The axes object contains an object of type line.

Input Arguments
