Publisher review:Matlab Finite difference weights finds finite difference (or interpolation) weights for an arbitrary set of nodes in one dimension. Given a vector of nodes x, a point of interest xi, and a nonnegative order of derivative m, this function returns weights such that an inner product with the values f(x) returns an approximation to f^(m)(xi). Based on the recursive formula due to Fornberg (A Practical Guide to Pseudospectral Methods, Cambridge University Press). Examples from the file:% First derivative near a boundaryh = 0.4; x = h*(0:5)'; w = fdweights(x(2),x,1)[ w'*exp(x) exp(x(2)) ]% Interpolationx = [0 0.25 1 1.5 2.5]'; w = fdweights(0.5,x,0)[ w'*sin(x) sin(0.5) ] Requirements: ยท MATLAB Release: R2006b
