matlab实现topsis

Sure, I can help you with that. TOPSIS (Technique for Order Preference by Similarity to Ideal Solution) is a multi-criteria decision-making method used to evaluate alternative solutions based on multiple criteria. To implement TOPSIS in MATLAB, you can follow these steps:

1. Define the decision matrix that contains the performance of each alternative on each criterion.
2. Normalize the decision matrix by dividing each element by the corresponding column sum.
3. Determine the weighted normalized decision matrix by multiplying each element in the normalized decision matrix by the corresponding weight of the criterion.
4. Determine the ideal and anti-ideal solutions by finding the maximum and minimum values for each column in the weighted normalized decision matrix.
5. Calculate the distance of each alternative to the ideal and anti-ideal solutions.
6. Calculate the relative closeness of each alternative to the ideal solution.
7. Rank the alternatives based on their relative closeness.

I hope this helps! Let me know if you have any further questions.
