.SH NAME
\fBquadrature_option_type\fP - send options to the integrate function
.\" skip: @cindex  quadrature formulae

.SH SYNOPSYS

The \fBquadrature_option_type\fP class is used to send options to
the \fBintegrate\fP function see integrate(4).
This class allows to set the family (Gauss, Gauss-Lobatto, etc)
and the polynomial degree that is exactly integrated.
See also the see quadrature(2) for more on quadrature formulae.
