#include <codecogs/maths/special/errorfnc_inv.h> #include <stdio.h> int main( ) { // display the value of the function at important points printf("x = 0 y = %.15lf\n", Maths::Special::errorFnC_inv(0.0)); printf("x = 1 y = %.15lf\n", Maths::Special::errorFnC_inv(1.0)); printf("x = 2 y = %.15lf\n\n", Maths::Special::errorFnC_inv(2.0)); // display several values of the function // at equally spaced abscissas with a step of 0.1 for (double x = 1.1; x < 1.99; x += 0.1) printf("x = %.1lf y = %.15lf\n", x, Maths::Special::errorFnC_inv(x)); return 0; }
Output
