• List MDiffElementEST[matrixIN_,varno_]
  Returns the list of the different elements in the (varno). row of the specified matrixIN 
  EF – NONE
• List MPolluteEST[mx_,row_,ratio_]
  Assigns a 0 or 1 (with equal probabilities) to the randomly selected "ratio" of the elements of the matrix "mx" and returns the new "polluted" matrix.If "mx" is a List, then "row" is not relevant.
  *EF – NONE;
• List MSelectEST[MatrixIN_,varno1_,varval1_, varno2_] 
  Returns the list of "varno2" variables from the "MatrixIN" where "varno1" values equal to "varval1" 
  EF – NONE / AppendRows from LinearAlgebra`MatrixManipulation` (Optional)
• List MSwapEST[MatrixIN_,row1_,row2_] 
  Swaps the rows "row1" and "row2" in matrix "MatrixIN" 
  EF – NONE

Important!!!

Assumed form of the MatrixIN: ; (i.e., values for the same variable are stored in ROWS, NOT in COLUMNS!)
