topsis.main("file_path", "weights", "impacts", "output.csv")
```

## Example

#### sample.csv

A csv file showing data for different mobile handsets having varying features.

| Model  | Storage space(in gb) | Camera(in MP)| Price(in $)  | Looks(out of 5) |
| :----: |:--------------------:|:------------:|:------------:|:---------------:|
| M1 | 16 | 12 | 250 | 5 |
| M2 | 16 | 8  | 200 | 3 |
| M3 | 32 | 16 | 300 | 4 |
| M4 | 32 | 8  | 275 | 4 |
| M5 | 16 | 16 | 225 | 2 |

weights vector = [ 0.25 , 0.25 , 0.25 , 0.25 ]

impacts vector = [ + , + , - , + ]

## Other notes

* Make sure the csv does not contain categorical values.
* Make sure your dataset has atleast 3 rows and 3 columns.
* The length of weights vector and impact vector must equal the number of columns in dataset.
* While writing weights vector or impact vectors, please make sure not to put extra spaces.
