exp¶
Purpose¶
Calculates the exponential function.
Format¶
-
y =
exp
(x)¶ - Parameters:
x (NxK matrix or N-dimensional array) – The values used to compute \(e^x\).
- Returns:
y (NxK matrix or N-dimensional array) – contains \(e^x\), the base of natural logs raised to the powers given by the elements of x.
Examples¶
x = eye(3);
y = exp(x);
1.000000 0.000000 0.000000
x = 0.000000 1.000000 0.000000
0.000000 0.000000 1.000000
2.718282 1.000000 1.000000
y = 1.000000 2.718282 1.000000
1.000000 1.000000 2.718282
This example creates a 3x3 identity matrix and computes the exponential function for each one of its elements.
