EVAL_POLY
Synopsis
Description
The eval_poly() function evaluates a polynomial, whose coefficients are contained in the array d, at
x, for example:
The order of the polynomial is passed in n.
Example
Return Value
A double value, being the polynomial evaluated at x.
#include <math.h>
double eval_poly (double x, const double * d, int n)
y = x*x*d2 + x*d1 + d0.
#include <stdio.h>
#include <math.h>
void
main (void)
{
}
double x, y;
double d[3] = {1.1, 3.5, 2.7};
x = 2.2;
y = eval_poly(x, d, 2);
printf("The polynomial evaluated at %f is %f\n", x, y);
