How to solve homogeneous linear equations with NumPy?
If I have homogeneous linear equations like this
array([[-0.75, 0.25, 0.25, 0.25],
[ 1. , -1. , 0. , 0. ],
[ 1. , 0. , -1. , 0. ],
[ 1. , 0. , 0. , -1. ]])
And I want to get a non-zero solution for it. How can it be done with NumPy?
linalg.solve only works on A * x = b where b does not contains only 0.
