Why R is 200 times slower than Matlab ?
I am switching from Matlab to R, but I found that R is 200 times slower than
matlab.
Since I am newbie to R, I must be missing some important programming tips.
Please help me out on this.

## make the full pair-wise permutation of a vector
## input_fc=c(1,2,3);
## output_fc=(
1 1 1 2 2 2 3 3 3
1 2 3 1 2 3 1 2 3
);
grw_permute = function(input_fc){
fc_vector = input_fc
