矢量开箱八度 [英] vector unpacking for octave

问题描述

八度(/matlab)用于处理多个返回值的符号

Octave(/matlab)'s notation for handling multiple return values

[a, b] = f(x)

建议f(x)返回的值在某种行向量中，并且Octave支持向量拆包(如Python的元组拆包).

suggests that the values returned by f(x) are in a sort of row vector and that Octave supports vector unpacking (like Python's tuple-unpacking).

我放的时候

[a, b] = [1, 2]

我知道

错误:常量表达式的输出参数数量无效

error: invalid number of output arguments for constant expression

八度音程支持向量解压缩吗?

Does octave support vector-unpacking?

如果是这样，正确的表示法是什么?

If so, what's the proper notation?

我在文档中找不到任何内容

I can't find anything in the documentation

推荐答案

我没有Octave可以测试，但是在MATLAB中，您可以解压缩"单元格数组.

I don't have Octave to test, but in MATLAB you can "unpack" cell arrays.

x = {1 2};
[x1,x2] = x{:}

x1 =
     1
x2 =
     2

您可以将数值矢量转换为x = num2cell([1 2]);的单元格数组.

You can convert numerical vector to a cell array as x = num2cell([1 2]);.

我必须补充一点，这适用于从7.0版开始的MATLAB.对于早期版本，您必须使用 DEAL 函数.

I have to add that this works for MATLAB starting from version 7.0. For earlier version you have to use DEAL function.
