Is element wise multiplication (%) speed in armadillo depends whether LAPACK/BLAS is installed? Im currently running armadillo without them installed and speed is awful.
Ok here is the simplest code, which takes eternity to calculate

```
    #include <iostream>
    #include "conio.h"

    #include "armadillo"

    using namespace arma;
    using namespace std;

    int main(int argc, char** argv)
    {

    int n=250; 
    mat X=ones(n,n);

    mat quan;

  for (int xi=1;xi<=256;xi++)
  {  
          quan = exp(X)%exp(X);
  }

  getch();

  return 0;
  }

```
