Support deep vectorization #14

Open fgnievinski opened 2 years ago

fgnievinski commented 2 years ago

push the loop over points deeper into the code, down at the quartic roots solver, replacing roots.m for mroots.m (attached) mroots.zip

fgnievinski commented 2 years ago

numerical algorithms will still require a shallow loop over points.

care is needed with elevations below spherical horizon (hint: discard upfront, returning NaN)
