CVVUTrend2 Method
Calculate an n'th order best-fit polynomial, specified X

Available since Oasis montaj version: 5.0.6
License: Available to anyone with an Oasis Montaj license.  

Namespace: Geosoft.Desktop.GXNet
Assembly: geosoft.desktop.gxnet (in geosoft.desktop.gxnet.dll)
Notes
Returns coefficients c[0] .. c[n] Y(x) = c[0] + c[1]x + c[2](x**2) + ... + c[n](x**n) The X scale is defined by a X VV (see Trend_VV for unitless X). The polynomial VV length is set to the number of coefficients (order + 1)
