blockCQUAD_quadrature
Extends from Icons.Block (Icon for blocks).
Information
Block for accessing the external GSL CQUAD doubly-adaptive integration routine, which can handle most types of singularities in the region of integration.
IMPORTANT!!!: The integrand-setup model 'CreateIntegrand' (or a duplicate) must be run before using GSL integration routines or blocks within a larger Modelica model. (Alternatively, one could edit integrand.c directly and then compile "by hand" in a command window:
gcc -fPIC -c integrand.c integration_mi.c
gcc -shared integration.o integration_mi.o -o libgsl_integration_MI.so [.dll for windows])
