Description

Functions

gwy_cdlines ()

GwyInventory *
gwy_cdlines (void);

Gets inventory with all the critical dimension evaluators.

Returns

Critical dimension evaluator inventory.

gwy_cdline_get_name ()

const gchar *
gwy_cdline_get_name (GwyCDLine *cdline);

Return cdline name (its unique identifier).

Parameters

cdline

A critical dimension evaluator.

Returns

The cdline name.

gwy_cdline_get_definition ()

const gchar *
gwy_cdline_get_definition (GwyCDLine *cdline);

Gets the name of the image file with critical dimension evaluator description.

Parameters

cdline

A critical dimension evaluator.

Returns

The cdline function definition.

gwy_cdline_get_param_name ()

const gchar *
gwy_cdline_get_param_name (GwyCDLine *cdline,
                           gint param);

Returns the name of a critical dimension evaluator parameter.

The name may contain Pango markup.

Parameters

cdline	A NL evaluator function cdline.
param	A parameter number.

Returns

The name of parameter param .

gwy_cdline_get_param_default ()

gdouble
gwy_cdline_get_param_default (GwyCDLine *cdline,
                              gint param);

Warning

gwy_cdline_get_param_default is deprecated and should not be used in newly-written code.

Returns a constant default parameter value.

Parameters

cdline	A NL evaluator function cdline.
param	A parameter number.

Returns

The default parameter value, unrelated to the actual data fitted. It is worthless.

gwy_cdline_get_param_units ()

GwySIUnit *
gwy_cdline_get_param_units (GwyCDLine *cdline,
                            gint param,
                            GwySIUnit *siunit_x,
                            GwySIUnit *siunit_y);

Derives the SI unit of a critical dimension parameter from the units of abscissa and ordinate.

Parameters

cdline	A critical dimension evaluator.
param	A parameter number.
siunit_x	SI unit of abscissa.
siunit_y	SI unit of ordinate.

Returns

A newly created GwySIUnit with the units of the parameter param . If the units of param are not representable as GwySIUnit, the result is unitless (i.e. it will be presented as a mere number).

Since: 2.5

gwy_cdline_get_nparams ()

gint
gwy_cdline_get_nparams (GwyCDLine *cdline);

Return the number of parameters of cdline .

Parameters

cdline

A critical dimension evaluator.

Returns

The number of function parameters.

gwy_cdline_fit ()

void
gwy_cdline_fit (GwyCDLine *cdline,
                gint n_dat,
                const gdouble *x,
                const gdouble *y,
                gint n_param,
                gdouble *params,
                gdouble *err,
                const gboolean *fixed_param,
                gpointer user_data);

Performs a critical dimension evaulation (fit).

Parameters

cdline	A critical dimension evaluator.
n_dat	The number of data points (number of items in x and y ).
x	Abscissa points.
y	Ordinate points.
n_param	The number of parameters. This argument is ignored as the evaluator knows how many parameters it has, it is safe to pass 0.
params	Array to store fitted parameter values to.
err	Array to store parameter errros to, may be NULL.
fixed_param	Which parameters should be treated as fixed. It is ignored, pass NULL.
user_data	Ignored, pass NULL.

gwy_cdline_fit_with_caldata ()

void
gwy_cdline_fit_with_caldata (GwyCDLine *cdline,
                             gint n_dat,
                             const gdouble *x,
                             const gdouble *y,
                             gdouble *params,
                             gdouble *err,
                             GwyCurveCalibrationData *cdata);

Performs a critical dimension evaulation (fit), allowing user to pass uncertainties.

Parameters

cdline	A critical dimension evaluator.
n_dat	The number of data points (number of items in x and y ).
x	Abscissa points.
y	Ordinate points.
params	Array to store fitted parameter values to.
err	Array to store parameter errros to, may be NULL.
cdata	Curve calibration data, may be NULL.

gwy_cdline_get_value ()

gdouble
gwy_cdline_get_value (GwyCDLine *cdline,
                      gdouble x,
                      const gdouble *params,
                      gboolean *fres);

Calculates critical dimension function value in a single point with given parameters.

Parameters

cdline	A critical dimension evaluator.
x	The point to compute value at.
params	Evaluator parameter values.
fres	Set to TRUE if succeeds, FALSE on failure.

Returns

The function value.
