GwyInventory* gwy_cdlines (void);
Gets inventory with all the critical dimension evaluators.
Returns : |
Critical dimension evaluator inventory. |
const gchar* gwy_cdline_get_name (GwyCDLine *cdline);
Return cdline name (its unique identifier).
|
A critical dimension evaluator. |
Returns : |
The cdline name. |
const gchar* gwy_cdline_get_definition (GwyCDLine *cdline);
Gets the name of the image file with critical dimension evaluator description.
|
A critical dimension evaluator. |
Returns : |
The cdline function definition. |
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.
|
A NL evaluator function cdline. |
|
A parameter number. |
Returns : |
The name of parameter param .
|
gdouble gwy_cdline_get_param_default (GwyCDLine *cdline, gint param);
gwy_cdline_get_param_default
is deprecated and should not be used in newly-written code.
Returns a constant default parameter value.
|
A NL evaluator function cdline. |
|
A parameter number. |
Returns : |
The default parameter value, unrelated to the actual data fitted. It is worthless. |
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.
|
A critical dimension evaluator. |
|
A parameter number. |
|
SI unit of abscissa. |
|
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
gint gwy_cdline_get_nparams (GwyCDLine *cdline);
Return the number of parameters of cdline
.
|
A critical dimension evaluator. |
Returns : |
The number of function parameters. |
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).
|
A critical dimension evaluator. |
|
The number of data points (number of items in x and y ).
|
|
Abscissa points. |
|
Ordinate points. |
|
The number of parameters. This argument is ignored as the evaluator knows how many parameters it has, it is safe to pass 0. |
|
Array to store fitted parameter values to. |
|
Array to store parameter errros to, may be NULL .
|
|
Which parameters should be treated as fixed. It is ignored,
pass NULL .
|
|
Ignored, pass NULL .
