ZernikePolynomial

MATLAB

zp_out = ZernikePolynomial(noll_order,rho,theta)

Description

Returns the value of the Zernike polynomial of order noll_order at normalized radius rho and angle theta: 0<=rho<=1 0<=theta<=2pi. rho and theta may be scalar or matrix quantity.

Parameters

Parameters	Description
noll_order [scalar]	Noll order for required Zernike polynomial
rho [matrix]	Radius values
theta [matrix]	Theta values

Return Values

Return Values	Description
zp_out [vector]	Zernike polynomial values

Examples

rad = sqrt(x.^2+y.^2);
theta = atan2(y,x);
rho = rad./ApRad;
z = ZernikePolynomial(5,rho,theta);
