| 1 | The Schr?dinger equation is a linear equation. | |
| 2 | Now, how do I solve a linear system matrix times x, y equals zero? | |
| 3 | Let's take a linear function of x, y, and z. | |
| 4 | OK, so we've seen how to multiply matrices, and how to write linear systems in matrix form. | |
| 5 | Well, in life, a lot of things are related by linear formulas. |
