Abstract

The Gauss-Seidel iteration process is specialised to fit unique surfaces in the least square sense to irregularely spaced data. The Fortran IV version of the specialised algorithm, called iterative one parameter least square process, is described for immediate computer use. The new algorithm requires so few storage locations that a 32 K computer memory without any peripheric device is sufficient to store 3000 data points and to solve a system of normal equations of order up to 1500. The surface fitting is illustrated by a numerical example.
