Hi I have a vector;
x = [2 4;3 -8; 1 2; 2 4;]
I need to produce two vectors like the ones to the left and right below. To get the vector on the right it is x_r = [2*-8 3*2 1*4] and same process for left(x_l) the arrows show what needs to be multiplied by what.
If the number of rows (columns will always = two) increase or decrease or the numbers change I need to account for this. Is there a way where I can do this by vectorization or will I be stuck with loops.
