Hi, I have a symbolic expression
I would like to isolate the coefficients of the variables (x, r and y (y's coefficient is 0)). How do I do that? I've tried using coeffs but that only lets me specify one variable. It would also be ok if I got two vectors back:
[ -2 , 1 , 7/4]
[x , r , 1]
even if they don't include y. Thanks!
