Because sym2poly returns numeric double-precision results, it approximates exact rational coefficients with double-precision numbers. c = sym2poly(1/2*x^3 - 2/3*x - 5) c = 0.5000 0 -0.6667 -5.0000. Input ... Esegui il comando inserendolo nella finestra di comando MATLAB.

% -*- texinfo -*- % @deftypefn {Function File} {} @var{c} = sym2poly (@var{p}, @var{x}) % Returns the coefficients of the symbolic polynomial expression @var{p} % as a vector. If there is only one free variable in @var{p} the % coefficient vector @var{c} is a plain numeric vector.

sym2poly. returns a row vector containing the numeric coefficients of a symbolic polynomial. The coefficients are ordered in descending powers of the polynomial's independent variable. In other words, the vector's first entry contains the coefficient of the polynomial's highest term; the second entry, the coefficient of the second highest term; and so on.
