Dear all,
Is it possible to extract the coefficients of an equantion defined as below:
syms x1 x2
eq = 2*x1 + x2 <= 0
By using coeffs and sym2poly did not work when it has the relational operator "<=".
c = coeffs(eq)
c = sym2poly(eq)

How about -
syms x1 x2
eq = 2*x1 + x2 <= 0
out = flip(coeffs(lhs(eq)))

Maybe it is appropriate to work in a reverse order, e.g.:
syms x1 x2
Coeff = [2;1];
eq = [x1, x2]*Coeff<=0
