I correct a little my code, in R code, i use "as.matrix" for ZT, so i haven't
got "segment fault" but it seems that i transmit only the first colon and
because "ncol" gives "1" and not "2".
So what happen ?
Programs
==== R CODE - test.R =====
X<-c(4,2,3,2)
Z<-c(40,21,30,20)
dX<-c(2,1,1)
dyn.load("test.so")
Phi<-function(z,a,b)
{
Phi<-z
}
VPEfron<-function(XType,ZType,dXType,G,c0,c1)
{

.Call("VPCEfron",body(f.check),as.double(XT),as.matrix(ZT),as.integer(dXT),as.integer(tailleS),new.env())
}
GG<-function(z) G(z,c0,c1)
VPEfron<-VPCEfron(GG,XType,ZType,dXType,length(XType))
}
resultat<-VPEfron(X,Z,dX,Phi,0,0)
