Introduction to the operation method of expressing e in Matlab

Method for calculating the natural number e In programming, the natural number e needs to be frequently used, which is an important constant in mathematics. For Matlab users, it is useful to know how to calculate e. This article will introduce different methods to calculate the natural number e in Matlab, including using built-in functions and custom functions. Help everyone master the skills to calculate e efficiently and accurately in Matlab.

After opening Matlab, enter e directly in the command line window and press Enter. You can see undefined variables displayed, as shown in the figure:

e Natural numbers

If you only express the natural number e, it can be expressed by exp(1), enter it in the command line window, and press the Enter key to see that the value of e is close to 2.7183, as shown in the figure:

The logarithmic function with e as the base

The logarithmic function with e as the base can be expressed by log(n), such as entering log(10 in the command line window ), press Enter to get the result 2.3026, as shown in the figure:

Exponential function with e as the base

Exponential function with e as the base. It can be represented by exp(n). For example, enter exp(5) in the command line window to represent the fifth power of e, as shown in the figure:

You can also verify that e is The base exponential function and logarithmic function representation form, enter log(exp(1)) in the command line window, press the Enter key, you can see that the result is 1, as shown in the figure:

Continue to enter log(exp(2)) in the command line window and press Enter. You can see that the result is 2, as shown in the figure:
