Polynomial with real coefficients —> array w/ real coeff
I could not find a suitable program to get the real coefficients of a polynomial in form of an array.
So I prepared one, indeed somewhat "bulky", but working smoothly. As the variable of the polynomial may already be defined in the current directory, the program changes its original name in the expression into another weird dummy variable X__, to be itself transformed back, at the end, to its original name after adequate string manipulations. Enter for example '2*(t+4*(5+10))7*t^6' Press P—>ARR To get '2*(t+4*(5+10))7*t^6' (original expression in stack level 2) '7*t^6+2*t+120' (simplified expression in stack level 1) :[ana0]: [ 7 0 0 0 0 2 120 ] (coefficients requested with label). The program will also detect incorrect similar variable names and give a corresponding message warning (as only 1 variable is allowed). Regards, Gil Campart
