Provide a function that takes in as input a matrix (as a numpy array) and returns `True` if the matrix is nonnegative and `False` otherwise. A function like the following...
Provide a function that takes in as input a matrix (as an numpy array) and returns `True` if the matrix is doubly nonnegative and `False` otherwise. A function like the...
It would be helpful to have a function that provides the mutual overlaps (inner products) of a list of numpy arrays (representing vectors of quantum states). Something like the following:...
There appears to be a bug in how the entangled value of an extended nonlocal game is calculated. Here is a specific example: ```python import numpy as np from toqito.states...
Closes #650
Allow the user to generate a random positive semidefinite (PSD) operator.
The nonnegative rank of a matrix, $A$, is defined as the smallest integer $k$ such that there exists nonnegative matrices $L$ and $R$ where $L$ is a $n \times k$...
The note ``` You do not need to use ‘%.2f’ % when you use this function. .... ``` It appears all over the place, and I find this a bit...
Define a function and associated unit tests to compute the *[spark](https://en.wikipedia.org/wiki/Spark_(mathematics))* of a matrix. Note that the spark is NP-hard to compute in general. Here is a candidate function for...
