WebSep 27, 2024 · What can we learn from these examples? The most obvious one is that the iteration needed for the conjugate gradient algorithm to find the solution is the same as the dimension of matrix A.That’s why we don’t need to safeguard our algorithm from infinite loop (using max iteration for instance) in LinearCG function. In fact, if A has only r distinct … WebI am not sure if these are intended to be supported use cases, but as a part of #98775, I experimented with cond (). This is not blocking any use case.
