Use of NAG Library

The NAG mathematical library is still used in a few MIDAS commands. A list of these programs and routines are given below:

Program	Package	NAG Routines
fitimag	Fit	e04fdf, e04fcf, e04gcf, e04hev,
		e04gbf, e04gef, e04gdf, e04ycf,
		e04jaf, e04hbf, e04jbf, e04kaf,
		e04hcf, e04kbf, e04kcf, e04kdf
genran	General	g05cbf, g05ddf, g05daf, g05dbf,
		g05def, g05edf, g05eyf, g05ecf,
		g05dff
echripp1	Echelle	e04gdf

A set of dummy routines are provided for sites that do not have a NAG library. This implementation enables sites to use the FIT package even without the NAG library (in this case, only the Newton-Raphson method is supported).
