i have 2 columns that i am performing an element-wise foldchange analysis on columns A & B. if the result is less than 1 then the operation must be reversed. i have; 1. z=B./A % divide each element of B by corresponding A element 2. if z< 1 % if Z is less than 1 3. A./B*-1 % then divide A element by corresponding B element and multiply by -1 end
but i get no response from matlab. this should be easy but it's not. as always thanks for your time and input jb
