| Abstract: | Bicubic COONS curve surfaces have enough smooth nd continuity propety,thecalculation is simple and convenient,and it is easy to realize on computers. The design of fitting ellip soid with bicubic COONS curve surface is written in FORTRAN77,which includes one main program and three subroutines(vw,aaand mat ).The program has a operation service,and the performance is very efficient. |
