point2 = point1.offset(vector) # point1本身不改变 point3 = point1.offset!(vector) # point1本身被改变 还有很多比重要的方法如: transform、project_to_line、project_to_plane、on_line?、on_plane? 小伙伴可以下去实践一下,在后期的制作中也会讲解到 ...

虽然不如Python在数据分析方面流行,Ruby也有其独到之处。它拥有多个库和工具,如Darú,专门用于数据分析和处理。Darú提供了DataFrame和Vector数据结构,类似于Python的Pandas库,这使得Ruby在处理复杂数据集时变得更加强大和灵活。 三、自动化脚本 Ruby同样在自动化脚本编写领域显示出其强大的能力。这得益于其简洁的语法和广...
为了对抗加密段的攻击,那么就需要将每段加密段联系起来,这就有了密码块链模式。这种模式需要一个初始向量IV(Initialization Vector)来执行异或操作。 其加密过程公式为$$C_i = E_k(P_i \oplus C_{i-1})$$ 其中初始 $C_0 = IV$ 以AES-128-CBC为例。对于每一个16字节明文,首先和16字节的向量执行异或...
The Vector class represents a mathematical vector, which is useful in its own right, and also constitutes a row or column of a Matrix. Installation The matrix library comes pre-installed with Ruby. Unless you need recent features, you can simply require 'matrix' directly, no need to install...
