How to solve for scalar constant coefficient :: [1x11 matrix]=[1x11 matrix].*coefficient

Lets say I want to estimate a coefficient as good as possible according to [1x11 matrix]=[1x11 matrix].*coefficient

How would I go on about this?

For ease, we can call them matrix1 and matrix2

I tried the backslash thing, but got a vector of only NaN

Thanks!

Hi Guster, there may be something going on with your data, because (row vector)/(row vector) does give the required coefficient.
