sturm takes two or four arguments : P a polynomial expression or P/Q a rational fraction and a variable name or P a polynomial expression, a variable name and two real or complex numbers a and b.
If sturm takes two arguments, sturm returns the list of the Sturm sequences and multiplicities of the square-free factors of P (or P/Q) (in this case sturm behaves like sturmseq).
If sturm takes four arguments, it behaves like sturmab :
