Question: converting a horizontal matrix to vertical

Hello. I am trying to convert a 100*2  matrix to 2*100 matrix. I appreciate if you give me any idea. The reason is I need to find the pick of negative data at second column, and I am using following code:     NEG=[find(E(:,1)<0) E(E(:,1)<0,1)]; so for using following code I need my matrix be 2*100 EE=findpeaks(NEG(:,2));
