syms q0 q1 q2 
e=q0 - 0.00784*q1*(94.1*q0^2 + 368.0*q1^2 + 149.0*q2^2) + 0.00344*q1*(1511.0*q0^2 + 5900.0*q1^2 + 2400.0*q2^2) + 0.0902*q0*(106.0*q0^2 + 175.0*q1^2 + 74.7*q2^2) - 1.45*10^(-4)*q2*(- 2044.0*q0^2 + 2199.0*q1^2 + 711.0*q2^2) - 0.103*q0*(2488.0*q0^2 + 2011.0*q1^2 + 934.0*q2^2) + 3.2*10^(-4)*q2*(2488.0*q0^2 + 2011.0*q1^2 + 934.0*q2^2)
a=simplify(e)

You can also use

[coe,var]=coeffs(a)
coe=double(coe)
