[MITgcm-support] Matlab script for initializing float position? -- flt package

[Dustin Carroll]

Hi Yangxin,

I don't have a MATLAB script to generate the floats, but I have used flt
pkg
successfully in the past.

Your workflow is correct: 1) modify and compile/run write_float.F to
generate the floats,
2) convert to big-endian with convert_ini.m, and 3) read in trajectories
with read_flt_traj.m.

I do remember having to fix a few issues with the provided scripts along
the way.
You can email me directly if you need my old example scripts, etc.

Best,
Dustin
