sign - Sign function (signum function) - MATLAB - MathWorks
This MATLAB function returns an array Y the same size as x, where each element of Y is: 1 if the corresponding element of x is greater than 0.
sign - Sign 函数（符号函数） - MATLAB - MathWorks
此 matlab 函数 返回与 x 大小相同的数组 y，其中 y 的每个元素是： 1，前提是 x 的对应元素大于 0。 0，前提是 x 的对应元素等于 0。 -1，前提是 x 的对应元素小于 0。
sign - Sign of real or complex value - MATLAB - MathWorks
Sign Function. The sign function of any number z is defined via the absolute value of z: sign (z) = z | z |. Thus, the sign function of a real number z can be defined as follows: sign (z) = {− 1 if x <0 0 if x = 0 1 if x> 0.
What is the @ operator (at sign) in MATLAB? - Stack Overflow
2010年1月20日 · The @ operator creates a function handle, something that allows you to easily create and pass around a function call like a variable. It has many nice features, none of which are available to you unfortunately. This is because as you suspect, it was not introduced into matlab until version 7, the release immediately after yours.
matlab中sign函数用法 - CSDN博客
在MATLAB中，sign函数返回输入参数的符号，即： - 如果输入参数为正数，则返回1。 - 如果输入参数为负数，则返回-1。 - 如果输入参数为0，则返回0。 例如，sign(5)返回1，sign(-3)返回-1，sign(0)返回0。 使用方法： ```matlab y = sign(x) ``` 其中，x为输入参数，y为返回值。

Signum function. Syntax. Y = sign(X) Description. Y = sign(X) returns an array Y the same size as X, where each element of Y is: 1 if the corresponding element of X is greater than zero 0 if the corresponding element of X equals zero -1 if the corresponding element of X is less than zero For nonzero complex X, sign(X) = X./abs(X).
