NumPy作为Python数值计算领域的基础框架，凭借其强大的N维数组结构和丰富的函数生态系统，成为科学家、工程师和数据分析师的核心工具。然而，随着计算需求的快速增长，特别是在机器学习和大规模科学模拟领域，NumPy基于CPU的执行模式以及缺乏内置自动微分功能的限制愈发明显。 JAX正是为了解决这些问题而设计的。作为Google Research开发的数值计算库，JAX致力于将NumPy引入现代硬 ...

When it comes to learning to code in a new language, it makes sense to start at the beginning. Learning how to print in Python is most certainly the beginning. The “print” command, as in BASIC, is ...

量化投资的核心原理是通过数学模型和统计分析方法，识别市场中的模式和趋势，从而预测未来的价格走势。Python提供了多种库（如Pandas、NumPy、Matplotlib等）来处理和分析金融数据，以及构建和测试交易策略。

1、 在PyCharm中启动并打开一个Python项目。 2、 在Python项目中创建一个新文件，如test.py，并用编辑器打开它。 3、 在Python编辑区域输入from decimal import *，以引入decimal模块中的全部类和方法。 4、 输入cText = Context()，然后按回车键确认操作。 5、 输入dX = cText.create_decimal(9.615 ...

5、 输入multiplyX = cText.multiply (Decimal (-11), Decimal (3))，然后按下回车键执行操作。
