polclr

Clear Polynomial

SYNOPSIS:

int na;
double a[na];
polclr( a, na );

DESCRIPTION:

Set all coefficients of polynomial a to zero, up to a[na].

The polynomial is represented by an array containing its coefficients, together with a separately declared integer equal to the degree of the polynomial.
The coefficients appear in ascending order; that is,

2 na
a(x) = a[0] + a[1] * x + a[2] * x + ... + a[na] * x .
