[英]import function in octave
I am running matlab code in octave. 我在八度音程中运行matlab代码。 The import function is not implemented in core octave, I guess. 我想,导入功能没有在核心八度中实现。 Any idea how to use this matlabe function in octave? 知道如何在八度音阶中使用这个matlabe函数吗?
Here is what I have: octave-3.4.0:7> setup Importing packages: brml.* warning: the `import' function is not yet implemented in Octave 这就是我所拥有的:octave-3.4.0:7> setup导入包:brml。*警告:“导入”功能尚未在Octave中实现
