Use the FIND function

[felix]

out1=find(A==B)? i cant find how to write out2 :/ sorry bout i am new in matlab

[Matt J]

 out2=A(out1) %or B(out1)

[Matt J]

Or if you want 2D coordinates

   [i,j,out2]=find(A==B);

   out1=[i,j];

[Azzi Abdelmalek]

 [x,idx]=find(A==B)

[felix]

how can i make a function that accepts as input a vector of integers, which will return the largest and the second largest component of the vector for the first i think that is max1=max(max(C)) any idea for max2?

[Matt J]

It is more efficient to do

 max1=max(C(:));

Also, as a hint to the second part

C(C==max1)=-inf
