mso-font-kerning:0pt">一个矩阵(复数矩阵)是一个矩形网格中所有有序的一串数字。只要你喜欢,网格可以有很多行和列,这取决于你打算使用矩阵做什么。在数学的世界,矩阵几乎应用在每一个领域中。最常用的是线性代数,你可以解决多个未知的多个方程。他们可以被应用在几何中。这是我们要深入的,我们用第一个矩阵来表示点,使用第二个矩阵,表示修改这一点的方式。这就是所谓的<i>变形</i>。当你用很多点形成形状或图像,你可以在每个点上应用“变形”,结果通常是一些熟悉的东西,像一个旋转,拉伸,一个动作,甚至是他们的组合。这就对了,你可以使得他们同时变大和倾斜。<span lang="EN-US"><o:p></o:p></span></span></p>

mso-font-kerning:0pt">当你手写出一个矩阵,根据他们的行和列,整个矩阵是由两个巨大的方括号包围起来的数字矩阵。不幸的是,没有简单的方法做,所以当我写一个矩阵的时候,我在每一侧用竖直的栅栏代表方括号。不要太在意它,它只是要清楚矩阵开始和结束的地方。你会发现,<span lang="EN-US">Rainmeter</span>帮助文件做着同样的事情。<span lang="EN-US"><o:p></o:p></span></span></p>
