... We have seen operators in QM behave just like matrices, such as transposed, Hermitian, and eigenvalue problems, etc. In fact, we can formulate a QM problem completely in terms of matrix analysis: a state becomes a column matrix and an operator becomes a square matrix. This is particularly useful if ...
