Accurate calculations are done\nusing 'Richardson''s' extrapolation or, when applicable, a\ncomplex step derivative is available. A simple difference\nmethod is also provided. Simple difference is (usually) less\naccurate but is much quicker than 'Richardson''s' extrapolation\nand provides a useful cross-check. Methods are provided for\nreal scalar and vector valued functions.", "LazyLoad": "yes", "ByteCompile": "yes", "License": "GPL >= 2", "Copyright": "2006-2011, Bank of Canada. 2012-2022, Paul Gilbert",
