如何在MATLAB中将eig与nobalance选项一起使用? [英] How to use eig with the nobalance option as in MATLAB?

问题描述

在MATLAB中，我可以发出命令:

In MATLAB I can issue the command:

[X,L] = eig(A,'nobalance'); 

为了计算特征值而没有平衡选项

In order to compute the eigenvalues without the balance option.

NumPy中的等效命令是什么?当我运行eum的NumPy版本时，其结果与打开nobalance的MATLAB结果不同.

What is the equivalent command in NumPy? When I run the NumPy version of eig, it does not produce the same result as the MATLAB result with nobalance turned on.

推荐答案

NumPy当前无法执行此操作.正如霍奇勒所说，一段时间以来，已经有一张开放票.但是，可以使用外部库来实现.在这里，我写下了如何使用与NAG库的Python绑定来做到这一点

NumPy can't currently do this. As horchler said, there has been an open ticket open for this for a while now. It is, however, possible to do it using external libraries. Here I write up how to do it using the Python bindings to the NAG library

应该有可能使用与LAPACK的任何接口(例如Intel MKL等)执行类似的操作.

It should be possible to do something similar using any interface to LAPACK such as the Intel MKL etc.
