All of these decompositions offer a solve() method that works as in the above example.
For example, if your matrix is positive definite, the above table says that a very good
-choice is then the LDLT decomposition. Here's an example, also demonstrating that using a general
+choice is then the LLT or LDLT decomposition. Here's an example, also demonstrating that using a general
matrix (not a vector) as right hand side is possible.
