Colormaps for MATLAB

Multiple colormap sources are unified under one common syntax in this repository to make it easy to use perceptually uniform colormaps in MATLAB. Make sure to read the sources section and the acknowledgements, as this repository uses multiple external sources for colormaps.

Maintain as a git submodule

Install submodule

1. To add the Colormaps repository as a git submodule run:

git submodule add https://github.com/davidclemens/Colormaps.git <relativePathWithinSuperrepository>

This should create a .gitmodules file in the root of the superrepository, if it doesn't exist yet. 2. In that file add the branch = release line. So that it looks like this:

[submodule "<relativePathWithinSuperrepository>"]
	path = <relativePathWithinSuperrepository>
	url = https://github.com/davidclemens/Colormaps.git
	branch = release

Update submodule

1. If you want to pull the latest release from this repository to your submodule run

git submodule update --remote --merge
