mi32/trend.h - common include file for trend removal algorithm 'gettrend' computes the trend of a raster and return a polynomial and an offset. The returned polynomial is arranged in increasing order of varibles XY, Within an order, X is decreasing in its order, Y increasing in its order. e.g. if the polynomial is of order 3, then the returned polynomial is: where a,b,c,d,e,f,g,h,i,j are coefficients of the polynomial, which are stored in 'coef'. 'evalpoly' evaluates a polynomial of order n, at point (x,y). Definition at line 63 of file trend.h.
