## Re: Trouble with symbolic on the Octave

 Hello, Doug! Some examples below: 1) >> syms x y >> S=(x^2+x-exp(x))*(x+3) S = (sym)               / 2        x\   (x + 3)*\x  + x - e / >> F=collect(S) error: 'collect' undefined near line 1 column 3 >> it was expected F=x^3+4*x^2+(-exp(x)+3)*x-3*exp(x) 2) >> syms x y >> S=x*(x*(x-8)+10)-5 S = (sym) x*(x*(x - 8) + 10) - 5 >> SA=simplify(S) SA = (sym) x*(x*(x - 8) + 10) - 5 >> it was expected SA=x^3-8*x^2+10*x-5 3) >> sym x ans = (sym) x >> s=(x^3-4*x^2+16*x)/(x^3+64) s = (sym)    3      2   x  - 4*x  + 16*x   ----------------        3       x  + 64 >> F=simple(S) error: 'simple' undefined near line 1 column 3 >> it was expected F=x/(x+4) I'll appreciate any assistance!
