Hi,

I have below matrix:

0 20.0 55.0 15.0  102.0 90.0
7 10.0 58.5 10.8  120.3 89.6   
00 35.9 38.3 16.8  89.6  96.3 
2 38.6 42.8 5.40  63.5  95.4

I want to know the optimal combination of column1~4 which yield smaller values in column5, and higher value in column6.

Column 1~4 is the combination (in percentage), column 5~6 are the performance indexes.

Criterion of optimum(good performance): The column 5 should be smaller, and column6 should be higher. How to know which combination (column1~4) yield the good results

How do you calculate the performance indices from the first four columns?

To find the linear regression parameters for example:

M = [10.0 20.0 55.0 15.0
    20.7 10.0 58.5 10.8   
    9.00 35.9 38.3 16.8
    13.2 38.6 42.8 5.40];
C5 = [102.0; 120.3; 89.6; 63.5];
C6 = [90.0; 89.6; 96.3; 94.4];
B5 = M\C5;                          % Parameters For The Current Column #5
B6 = M\C6;                          % Parameters For The Current Column #6
