在学习Matlab的数学函数时，教程中提到取模（mod）与取余（rem）是不同的，今天在网上具体查了一下：通常取模运算也叫取余运算，它们返回结果都是余数.rem和mod唯一的区别在于: 当x和y的正负号一样的时候，两个函数结果是等同的；当x和y的符号不同时，rem函数 ...

r = rem(a,b) returns the remainder after division of a by b, where a is the dividend and b is the divisor. This function is often called the remainder operation, which can be expressed as r = a - b.*fix(a./b). The rem function follows the convention that rem(a,0) is NaN.

The operator rem is returning the remainder on division by a. In your example. The operator mod a is one that is used a great deal in number theory, but almost exclusively with m a positive integer. We say that a is congruent to b modulo m if b - a …

Structuralism is a theory in the philosophy of mathematics that holds that mathematical theories describe structures of mathematical objects. Mathematical objects are exhaustively defined by their place in such structures.

2021年1月8日 · You can use RemNote to study maths but the workflow is pretty different compared to other subjects. This semester I experimented a bunch on how to successfully do it and most of my strategies were without much success.

2022年9月29日 · rem() 函数的基础知识 . 余数的数学概念来自除法，表示一个数不能平均除以另一个数时的余数。例如，在 9 ÷ 4 中， 9 不是 4 的倍数，因此 4 不能平均分成 9 。你可以把两个 4 相加，得到 8 ，但是你仍然有一个 1 余数来得到 9 ，所以 1 就是我们的余数。

2019年4月21日 · There are 2 options I can come up with off the top of my head. 1: CSS calc () function. 2: Convert px to rem. @return $px / $base; This assumes 16px is the basis for your rem units, which you can change by passing a second argument into your rem call. Stripping the units makes the math work.
