This article mainly introduces "what is the two-dimensional matrix in python". In the daily operation, I believe that many people have doubts about what the two-dimensional matrix in python is. The editor consulted all kinds of data and sorted out a simple and easy-to-use operation method. I hope it will be helpful for you to answer the doubt of "what is the two-dimensional matrix in python?" Next, please follow the editor to study!

A brief introduction to 0jinnumpy

Numpy is the basic package for high-performance scientific computing and data analysis.

Most of the underlying code is written in C language and runs fast.

Strongly support the vectorized programming style, effectively replace the loop.

There are more data types than python.

The three commonly used objects in numpy are ndarray,matrix and ufunc

In this section, we introduce the matrix two-dimensional matrix. The matrix is summarized below.

The matrix object is more similar to the matrix in matlab and is always two-dimensional.

It is more concise to use array to do element-by-element operation and matrix to do matrix operation.

Unless you have a lot of matrix operations, you should use array as much as possible.

First, create a matrix

Second, matrix basic operation

Third, the comparison between array and matrix

1 array matrix is always two-dimensional, while the matrix can be one-dimensional, two-dimensional, or three-dimensional.

2 matrix array is a more basic type, which is actually implemented through array.

At this point, the study of "what is the two-dimensional matrix in python" is over. I hope to be able to solve your doubts. The collocation of theory and practice can better help you learn, go and try it! If you want to continue to learn more related knowledge, please continue to follow the website, the editor will continue to work hard to bring you more practical articles!
