Bivar_params – This document briefly describes all Bivar parameters. DescriptionBivar currently supports two parameters. The current values may be retrieved using one of the routines IDGETI or IDGETR. Parameter values may be reset using the routine IDSETI or IDSETR. The Bivar parameter descriptions appear below in alphabetical order. Each description begins with a line giving…
Bivar – Provides bivariate interpolation and smooth surface fitting for values given at irregularly distributed points. The resulting interpolating function and its first-order partial derivatives are continuous. The method employed is local, i.e. a change in the data in one area of the plane does not affect the interpolating function except in that local area….
Autograph_params – This document briefly describes all Autograph internal parameters. DescriptionThe Autograph control parameters reside in the labeled common block AGCONP. There are currently 485 of them, of which 336 are "primary" and 149 are "secondary". Primary control parameters have default values and are subject to change by a user program to produce some desired…
