• Standardize

  public static double[][] Standardize(int nrow,

  Note the formalas used (since these vary between implementations):
  reduction: (vect - meanvect)/sqrt(nrow)*colstdev
  colstdev: sum_cols ((vect - meanvect)^2/nrow)
  if colstdev is close to 0, then set it to 1.

  Parameters:

  nrow - number of rows in input matrix

  ncol - number of columns in input matrix

  A - input matrix values
