Exactly. We can replace the use of imaginary numbers with matrix operations.
Schrödinger himself was annoyed by the imaginary part in his equation. In a letter to Lorentz on 6 June, 1926, Schrödinger wrote:
What is unpleasant here, and indeed directly to be objected to, is the use of imaginary numbers.ψ is surely fundamentally a real function”.
Surely he knew that he could have done without imaginary numbers.
