This is the second part in a series of videos giving examples of developing colormaps in MATLAB. In this video:

• We review the colormaps that are to be made
• Show the four expected calling syntaxes for the function
• Show how to use VARARGIN to make deal with different numbers of input arguments
• Show error catching
• Show different branches of code to be followed based on inputs
• Developing an algorithm with cell mode to test an algorithm
• Testing
• Documentation
