Description

This model of the ISIS CRISP reflectometer demonstrates the use of the Multilayer_Sample component.

The algorithm of the component requires complex numbers, facilitated by the
GNU Scientific Library (GSL). To link
your the instrument with an installed GSL, you should use MCSTAS_CFLAGS like

MCSTAS_CFLAGS = -g -O2 -lm -lgsl -lgslcblas
