Description

Translating from matlab to cpp for hyperbolic1D, parabolic2D, and helmholtz2D_wifi. hyperbolic1D and parabolic2D are ready for review. I am still working on the last one.

_From .../mole/build

cmake ..
make
cd /examples/cpp ./executable
in this case it is parabolic2D or hyperbolic1D._

Added/updated tests?

_We encourage you to test all code included with MOLE, including examples.

• Yes
• No, and this is why: I am translating these examples from matlab to cpp. The test I thought was appropriate was comparing to the output of the matlab codes to it's cpp counterpart. If this is a poor way of objectively testing I can adopt a different method for this task.
• I need help with writing tests

Hi @CaywoodR thank you for your contribution!

Please modify the name of the PR to reflect that it is not python and to be a bit more specific. Thank you!

[valeriabarra]

Hi @CaywoodR , thank you for your contribution. Please update this branch with the main (you can use git merge or git rebase <- recommended, but then it requires a force-push). Please let me know if you need any assistance with that. Thank you

[CaywoodR]

@valeriabarra Would I only use rebase on the local branch of the mole fork?

Yes, but first you need to make sure your upstream and origin are set up correctly (check git remote -v to see where you're pointing to). Then you update the main branch by doing git fetch (and confirm that the latest commit you see in git log is what appears to be merged last in the public repo) and then you rebase the main branch onto yours.

[CaywoodR]

On my current path /home/caywood/Math693B/mole/build/examples/cpp, I input git remote -v. It output

origin git@github.com:CaywoodR/mole.git (fetch)
origin git@github.com:CaywoodR/mole.git (push)

So, git fetch will update the main branch on my fork?

[valeriabarra]

Do
git remote add upstream <ORIGINAL_PUBLIC_REPO_URL>

[CaywoodR]

I input

git remote add upstream https://github.com/csrc-sdsu/mole.git

I did not see anything happen, but I input it again to get:

error: remote upstream already exists.

So, the upstream remote is now there.

You can verify by running

git remote -v

(the -v stands for verbose).

If you have more questions on how to update your branch, it's probably easier if you could stop by office hours and I can assist. Thank you

[CaywoodR]

run

git remote -v

the output is:

origin git@github.com:CaywoodR/mole.git (fetch)
origin git@github.com:CaywoodR/mole.git (push)
upstream https://github.com/csrc-sdsu/mole.git (fetch)
upstream https://github.com/csrc-sdsu/mole.git (push)

Sounds good. Thanks for the assistance!

Hi @CaywoodR , you need to update this branch with main again. Then, please also reduce the number of commits to a minimum number of significant commits that reflect your work (even just one if you'd like). You can use the interactive rebase, with git rebase -i for that and then force-push.

Then, I am not sure if @jbrzensk has any other comments. It looks good for me. Thank you

[valeriabarra]

Can you please also edit the title of the PR to reflect that this is not a draft anymore?

[CaywoodR]

Hi @valeriabarra, when I use

git rebase -i

I see this. I do not see any commits.

Hi @valeriabarra, I tried rebasing, but I am having issues once I go to force-push. I included images of the following sequences I see after saving the file and then prompting the force.
