Fix cBathy Angle Seed

[KateBrodie]

@bergsmaE @RobHolman

Here is a space for you to discuss and test new approaches for determining the seed angle in findKAlphaPhiInit.m.

Please post any results/figures for us all to see here!

Ok, I did some first tests on data I have from Porthtowan and it seems very promising. I can get the incident wave angle. Bear in mind that this is for nice swell.

Shore normal case:

Note: I do use all the pixels in the tile (so not limited by params.maxNPix)

@RobHolman , can you send me the xy and v related to the tile and case where the problem of the alphaSeed occured?

Thanks,

Erwin

I have worked a bit on the plotting of the results of the cases above and the provided "problem" case. It seems to work pretty well:

@RobHolman if you have more special cases, please send them to me. I will finish the script that has as input "v" and an angle seed as output.

ADDED makeAlphaSeed.m to the branch (radon_alpha_seed)--> gives angle in radians

Cheers,

Erwin

Clearly, I have no idea what I am doing with gitHub, apparently, I closed the issue :-), luckily I could reopen it.

@bergsmaE this is looking great!

@RobHolman & @bergsmaE when you have tested enough "problem" cases and are happy with it, please then submit a pull request to merge this back into development. Tag someone to test it, and then we will run this on the cases from the original cBathy paper to make sure we aren't suddenly getting vastly different or incorrect results.

@KateBrodie Did we do a pull request already for the alphaSeed?

I think we @RobHolman, tested it I haven't found any issues after with other datasets.

alphaSeed is available in v2.0.
