Dear All,
I have modified the code as following. Since I found the old code had the
memory allocation issue, I calculated each term of the matrix with dim 4.
The speed is pretty much good now. But since I am not familiar with Rcpp,
the code sometimes will get error, like
*** caught segfault ***
a
I tried out that if the dim of the matrix less than or equal to 4, inv()
and solve() have the same speed.
Best wishes!

CharacterVector out(nr) ;
for( int i=0; i
