Description [src]

This function computes the integral of the function integ->f over the interval [xi, xf] and [yi, yf] using the Vegas algorithm from the Cuba library.

Parameters

integ

Type: NcmIntegrand2dim

A pointer to NcmIntegrand2dim.

The data is owned by the caller of the function.

xi

Type: gdouble

Gbouble which is the lower integration limit of variable x.

yi

Type: gdouble

Gbouble which is the lower integration limit of variable y.

xf

Type: gdouble

Gbouble which is the upper integration limit of variable x.

yf

Type: gdouble

Gbouble which is the upper integration limit of variable y.

epsrel

Type: gdouble

Relative error.

epsabs

Type: gdouble

Absolute error.

nstart

Type: const gint

Number of samples to start the first round of integration with.

result

Type: gdouble*

A pointer to a gdouble in which the function stores the result.

The data is owned by the caller of the function.

error

Type: gdouble*

A pointer to a gdouble in which the function stores the estimated error.

The data is owned by the caller of the function.

Return value

Type: gboolean

Whether the integration was successful.
