ezplot('x^3+3*x^2+10*x'/'x^4+4',[-4,4])
??? Error using ==> mrdivide
Matrix dimensions must agree.

any help?

one of the solutions
- your use of '/' does not make sense...

ezplot('x^3+3*x^2+10*x/x^4+4',[-4,4]);

Try
ezplot('x^3+3*x^2+10*x/(x^4+4)',[-4,4])

or
ezplot('(x^3+3*x^2+10*x)/(x^4+4)',[-4,4])
if that's what you meant.
