Polynomial fit is a standard in MATLAB. How to work with matrix data in the same way as we do
VEC=polyfit(x,y) ?
BIPFIT is written in this way: it FITs a bipolynomial (matrix BIP) to a data matrix DAT:
BIP=bipfit(DAT,VERHOR)
where VERHOR=size(BIP), defining VERtical and HORizontal polynomial orders.
The surface SUR, which is the BIPolynomial approximation to DAT, can be calculated as:
SUR=bipval(BIP,size(DAT));
Based on:
POLIFIC
