Contents
Syntax
varargout = BHCOEFS(BCs,h,D,nu,order)
Description
varargout = BHCOEFS(BCs,h,D,nu,order) returns the individual coefficients of the isotropic biharmonic with elastic boundary constants for a biharmonic operator matrix with grid spacing h, stiffness coefficient D and Poisson's number nu. varargout is a variable sized list of coefficients for the given order.
Input Arguments

- h : Grid spacing
-
D : Stiffness constant
- nu : Poisson's ratio
- order: Index of coefficient
