Hi, I am writing a program to determine the value of element A which is corresponding to the minimum value of element B. The answer must be as:

M =

0.031
508
However, the written code

 M = min(E,[],2)

gives this answer

M =

0.025
508

Could you please let me know the right code which is able to display the value of element A which is corresponding to smallest value of element B.

Thank you very much

This works:

E  = [  0.025   520
         0.027   531
         0.029   560
         0.031   508
         0.033   600
         0.035   572
         0.037   523
         0.039   512
         0.041   582
         0.043   525];

[MinB,Idx] = min(E(:,2));
Result = E(Idx,:)

produces:

Result =

      31.0000e-003   508.0000e+000

as desired.
