I've composed a large list of functions in Mathematica that I'd like to have a c function evaluate. To my knowledge c and C++ reject the convention x^2 and prefer either x*x or pow(x,2). The functions are integer powers of a single variable. I'm using the command, Export["function_list.txt", Table[gflist[p], {p, 2, 5}], "CSV"] where "gflist[n]" generates the said set of functions for the case "n". The output file then looks like: [winesap:~] nmoore% cat function_list.txt 1/(8*d*l^3*Pi) 1/(8*l^3*Pi),-(-3 + d)/(16*d*l^3*Pi) (8 - 3*d)/(64*l^3*Pi),(-4 + d)^2/(64*d*l^3*Pi) -(-5 + d^2)/(64*l^3*Pi),(-5 + 30*d - 15*d^2 + 2*d^3)/(192*d*l^3*Pi),-(-5 + d)^3/(384*d*l^3*Pi) I don't mind pasting in the "case" statement required by c, but I don't have the free two days required to re-express all the carats (^). How can I have Mathematica express x^15 as x*x*x*x*x*x*x*x*x*x*x*x*x*x*x (the highest power of the polynomial is "n", I'd like to export the set of functions n=2 to n=30 or so - far too much typing for me) NT Moore University of Minnesota Physics
