Exp is an exponential function based on natural constant e in higher mathematics. Exp(x) represents the x power of e, and x can be a function. For example:

exp(2)=e^2,exp(f(x))=e^f(x)

Extended data:

1, in c language

Function name: exp

Working energy: exponential function

Usage: double exp (double x);

Library: math.h

Program example:

2. In MATLAB.

There is exp function in MATLAB.

If you enter: exp(0) in the command window.

Then output: 1.

In fact, the exp function in MATLAB and C is the same as the exponential function based on E in mathematics.
