Use Variables eqns = {x[1] + y[1] + z[1], x[1] + 3 z[1] + u[1]^2, z[1] - u[1] - 16, u[1] - 5}; Variables /@ eqns {{x(1),y(1),z(1)},{u(1),x(1),z(1)},{u(1),z(1)},{u(1)}} Bob Hanlon ---- Stuart Nettleton <Stuart.Nettleton at uts.edu.au> wrote: ============= Hi, I am a bit stuck on how to convert the following set of equations to a list of variables: eqns = { x[1] + y[1] + z[1], x[1] + 3 z[1] + u[1]^2, z[1] - u[1] - 16, u[1] - 5}; to give.. {{ x[1], y[1], z[1]},{x[1], z[1], u[1]},{z[1], u[1],}, {u[1]}} Any thoughts would be appreciated!
