Details

class GOffice.CSpline

classmethod destroyl(sp)

Parameters:

sp (GOffice.CSplinel) – a spline structure returned by go_cspline_init.

Frees the spline structure when done.

destroy()

Frees the spline structure when done.

get_deriv(x)

Parameters:

x (float) – the GOffice.value

Returns:

the interpolated derivative at x, or 0 if an error occurred.

Return type:

float

sp must be a valid spline structure as returned by go_cspline_init.

get_derivs(x, n)

Parameters:

• x (float) – a vector a values at which interpolation is requested.

• n (int) – the number of interpolation requested.

Returns:

a newly allocated array of the n interpolated derivatives which should be destroyed by a call to GLib.free when not anymore needed, or None if an error occurred.

Return type:

float

sp must be a valid spline structure as returned by go_cspline_init. The x values must be sorted in increasing order.

get_integrals(x, n)

Parameters:

• x (float) – a vector a values at which interpolation is requested.

• n (int) – the number of interpolation requested.

Returns:

a newly allocated array of the n-1 integrals on the intervals between two consecutive values stored in x. which should be destroyed by a call to GLib.free when not anymore needed, or None if an error occurred.

Return type:

float

sp must be a valid spline structure as returned by go_cspline_init. The x values must be sorted in increasing order.

get_value(x)

Parameters:

x (float) – The GOffice.value

Returns:

the interpolated GOffice.value for x, or 0 if an error occurred.

Return type:

float

sp must be a valid spline structure as returned by go_cspline_init.

get_values(x, n)

Parameters:

• x (float) – a vector a values at which interpolation is requested.

• n (int) – the number of interpolation requested.

Returns:

a newly allocated array of interpolated values which should be destroyed by a call to GLib.free when not anymore needed, or None if an error occurred.

Return type:

float

sp must be a valid spline structure as returned by go_cspline_init. The x values must be sorted in increasing order.
