Solve non square matrix with python: How to use numpy.linalg.lstsq()?

QUESTION

Solve non square matrix with python: How to use numpy.linalg.lstsq()?

Asked 2019-Apr-15 at 06:54

Requested behaviour
I would like to solve a non-square matrix with python. The matrix has two linearly dependent vectors.

Current State
I tried to use numpy.linalg.solve() first, but that only works for square matrices. Other StackOverflow posts recommended using numpy.linalg.lstsq().

issue
However, I do not understand how to implement numpy.linalg.lstsq() correctly. The function solves the last parameter correctly, but not the other parameters. One post recommendet this solution which I do not understand either.

Do I have to implemt a loop somehow?

Can someone provide me with a code example? How do solve this matrix problem using python?

My current Code

This is an underdetermined system of equations. This means that there are many solutions, and there is no such thing as "the" solution. The fact that Gaussian elimination and lstsq give different solutions does not mean that anything is wrong.

Let's generate and check various solutions:
