This blog has repeatedly mentioned Mathematica, a super mathematical software, but so far I have not found its Linux version, and wine seems useless. In fact, there are many Mathematica-like mathematical software in Linux, among which maxima is the one I use most. Here, I will briefly introduce various maxima functions for your reference and facilitate future queries. Install: sudo apt-Get install maxima-sh

I. Model 1. Prototype and model prototype refer to the actual object that people care about, study or engage in production and management in the real world. A model is a prototype substitute that constructs a part of the prototype's information for a specific purpose, abbreviated and refining it. The model can be divided into the material model (image model) and the ideal model (abstract model) according to the mode of replacing the prototype. The former includes visual model, physical mod

Prospect of mathematical automatic theorem proof and Prospect of mathematical theorem proof On the afternoon of June 23, July 2, Beijing elementary school started summer vacation. Sun and sun on the second floor kept shouting, which left me a lot of trouble. However, when I went upstairs, I found sun was playing a connected online game with my classmates, which aroused my memories of the past. In the 19

In Word2013, the user can enter mathematical symbols by using the mathematical symbol AutoCorrect feature. The user simply enters a simpler string, which can be automatically corrected to a more complex and difficult mathematical notation (such as ≥, ┴, ≈, etc.). By default, the mathematical symbol AutoCorrect feature

Common mathematical functions in GPU programming, gpu programming mathematical functions In GPU programming, functions are generally divided into the following types: mathematical functions, geometric functions, texture ing functions, partial derivative functions, debugging functions, etc. Skillful Use of GPU built-in functions can improve the speed and efficien
