Member of the polynomials class.

Syntax

[pieces, order] = mkpp(breaks, coefs)

Description

Constructs a piecewise polynomial.

Examples

Inputs

Name	Description
breaks	Specifies the points at which the piecewise polynomial breaks. breaks is a matrix.
coefs	Specifies the coefficients of the piecewise polynomial. coefs is a matrix. The size of coefs must equal the length of breaks.

Outputs

Name	Description
pieces	Returns the number of pieces of the polynomial. pieces is a scalar.
order	Returns the polynomial order. order is a scalar.

Examples

P = [2, 1, 0, 3; 1, -8, 0, 1];
[PIECE, ORDER] = mkpp([0, 1, 2], P);
X = -1:0.01:1;
plot(X, polyval(P(1, :), X), X, polyval(P(2, :), X))

[PIECES, ORDER] = mkpp([1, 2, 3], rand(2, 4))
