make_colorwheel

Generates colorwheel files (circular colorscales) based on individual colormaps

This function generates colorwheel files (circular colorscales) based on individual colormaps. All built-in MATLAB colormaps as well as custom schemes in the same format are supported e.g. the perceptually uniform cyclic colormaps of Fabio Crameri (vikO, brocO or corkO) available via http://www.fabiocrameri.ch/cycliccolourmaps.php

Examples:
make_colorwheel('parula','pdf')
make_colorwheel('jet','png')
make_colorwheel('winter','pdf')
make_colorwheel('vikO','pdf') => F. Crameri's vikO.mat required
make_colorwheel('corkO','pdf') => F. Crameri's corkO.mat required
make_colorwheel('brocO','jpeg') => F. Crameri's brocO.mat required
