Eigen_calcs

 It is still impossible for me to call Bing/Chat from the sidebar on the Edge

browser but I can access things by asking for Copilot.

Below, copilot is re-doing the Math is Fun example on eigenvalue and eigenvector.

                                                

There is python code to do this same calculation:

The last viewed possibility is the tensor product, which involves multiplying

to matrices, not necessarily of the same dimensions. 

The tensor product multiplies the second matrix by every element of the first matrix

                                                                                     

• In quantum mechanics, the tensor product represents the combined state of two quantum systems. For example, the state of a composite system consisting of two particles is described by their tensor product state.
• In quantum computing, tensor products are essential for representing quantum gates and quantum circuits. Quantum gates act on tensor products of qubits to perform quantum operations
