CVVUTrend Method

Calculate an n'th order best-fit polynomial, integral x.

Namespace:  Geosoft.Desktop.GXNet
Assembly:  geosoft.desktop.gxnet (in geosoft.desktop.gxnet.dll) Version: 2024.2.0.25
Syntax
Copy
public static void Trend(
	CVV vv_d,
	int order,
	CVV vv_c
)

public static void Trend(
	CVV vv_d,
	int order,
	CVV vv_c
)

Parameters

vv_d
Type: GeoEngine.Core.GXNetCVV
VV with input data
order
Type: SystemInt32
Order of the polynomial 0-9
vv_c
Type: GeoEngine.Core.GXNetCVV
VV to hold polynomial coefficients (returned).
Remarks
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 unitless (1 per element), i.e. 0,1,2,3,... The polynomial VV length is set to the number of coefficients (order + 1)
