ChangeLog

version 2.0, 2016-08-15
-----------------------------------
	- errors.m: new routine added to propagate uncertainties
	- derivnum.m: new routine added to compute partial derivatives, needed for error propagation
	- CO2SYS.m: slightly modified routine 
		* slight changes to allow error propagation
		* new option to choose K1 & K2 from Waters et al. (2014): fixes inconsistencies with Millero (2010) identified by Orr et al. (2015)

version 1.1, 2016-12-20
-----------------------------------
	- Original version of CO2SYS.m from van Heuven et al. (2011) 
	- downloaded on 20 Dec 2016 from CDIAC: http://cdiac.ornl.gov/ftp/co2sys/CO2SYS_calc_MATLAB_v1.1/
