Test symb2poly == polyToCoeff - compsystems - 12-12-2016 08:22 PM Hello symb2poly == polyToCoeff as vector poly2symb == coeffToPoly increasing: off & simplify flag: NONE This should only extract the coefficients of each term > symb2poly( (x^2) + (b*x/a) + (b/(2*a))^2, x ); -> poly1[1, 4*a*b/(4*a^2), b^2/(4*a^2)] // ok but why Rewrites the coefficients? The output should be -> poly1[ 1, b/a, (b/(2*a))^2 ] with normal normal( symb2poly( (x^2) + (b*x/a) + (b/(2*a))^2, x ) ); poly1[ 1, b/a, (b/(2*a))^2 ] RE: Test symb2poly == polyToCoeff (simplify flag: NONE) fails - parisse - 12-13-2016 07:07 AM The at is correctly displayed if textbook mode if off. |
