Usage

Enter csv filename followed by .csv extentsion, then enter the weights vector with vector values separated by commas, followed by the impacts vector with comma separated signs (+,-)

topsis sample.csv "1,1,1,1" "+,-,+,+"

or vectors can be entered without " "

topsis sample.csv 1,1,1,1 +,-,+,+
