 Usage:  {med,depths} = simdep(x{, mem})   
 
 Input:

  x                      n x p matrix (n observations of dimension p) 
                         
                         
  mem                    optional parameter that affects the amount of memory 
                         used by the routine; the values belongs to interval (0,1), 
                         where 0 represents the minimal memory requirements 
                         and the lowest speed of computation, 
                         and 1 the maximal memory requirements and highest speed. 
                         Default value is 1. 
                         The higher is the dimension of observations (p), 
                         the bigger is the effect of the maximal memory setting 
                         (mem = 1). 
                         
                         
 Output:

  med                    p x 1 vector containing the estimate of location 
                         
                         
  depth                  n x 1 vector containing for every observation the 
                         number of simpleces covering it
