CPolynomial:Remove
The Remove method removes the coefficient at index n.
|
value = CPolynomial:Remove( n ) |
n is the coefficient order to remove.
On success, the
numeric value of the removed coefficient is returned.
On failure, 0
is returned.
The following script fragment removes the value at index 3:
|
P = CPolynomial:new() |
-- create a CPolynomial object |
|
P:Set(0, 0.144) |
-- set coef[0] |
|
P:Set(3, -0.0045) |
-- set coef[3] |
|
Printf("N = %d", P:Count()) |
-- result: N = 2 |
|
v = P:Remove(3) |
-- remove coef[3] |
|
Printf("N= %d, x=%lg", P:Count(), v) |
-- result: N = 1, x=-0.0045 |
