| Oct 18, 2022 at 21:58 | comment | added | Mirar | Yes, I meant tridiagonal. Thanks. Just editted. | |

| Oct 18, 2022 at 21:55 | comment | added | Mirar | Agree on the first comment. I just showed a different variation of it. | |
| Oct 18, 2022 at 21:51 | comment | added | Federico Poloni | The formula you obtained can also be proved more quickly using $(A\otimes B)(C\otimes D) = (AC)\otimes (BD)$. | |

| Oct 18, 2022 at 20:10 | comment | added | Mirar | It is the matrix exponential as defined in the provided link. I am not sure what you mean be the second part of your question. The enteries can be any non zero real numbers. | |
| Oct 18, 2022 at 20:01 | comment | added | Steven Landsburg | What does $e^A$ mean? Is there a missing hypothesis about where the entries of $A$ come from? | |
