1. MATLAB：
MATLAB 是一种多范式数值计算环境，是一种用于技术计算的高性能语言。 MATLAB 名称代表矩阵实验室。它是由 MathWorks.Inc 公司的 Cleve Molar 于 1984 年开发的。它是用 C、C++、 Java编写的。它允许矩阵操作、函数绘图、算法实现和用户界面的创建。
2.八度：
Octave 是一种具有高级编程语言的软件，主要用于数值计算。它由 John W. Eaton 开发，用 C、C++、Fortran 语言编写。它提供了一个文本界面和一个实验性图形界面。它还用于解决各种数字问题的各种机器学习算法。它与 MATLAB 类似，但与 MATLAB 相比性能较慢。
MATLAB 和 Octave 的区别：
| S.No. | MATLAB | Octave |
| 1. | MATLAB is a matrix laboratory, referred to as language used for technical computations. | Octave is programming language used for numerical computations. |
| 2. | It was written in C, C++ and Java programming language. | It was written in C, C++ and Fortran Language. |
| 3. | It is not an open source language. | It is an open source language. |
| 4. | It consumes more memory when compared to octave. | It consumes less memory than MATLAB. |
| 5. | MATLAB has a very good interface. Hence, it is easy to operate. | Its interface is not that good as MATLAB. |
| 6. | In MATLAB, it is allowed to load the empty files. | In Octave, it is not allowed to load the empty files. |
| 7. | It does not support C-style auto-increment and assignment operators i.e x++, ++x, etc. | It supports C-style auto-increment and assignment operators i.e x++, ++x, etc. |
| 8. | The execution speed is faster than Octave. | The execution speed is slower than MATLAB. |
