TREND ANALYSIS USING DOUBLE FOURIER SERIES 



LANGUAGE - FORTRAN IV 

 COMPUTER - GE 625 



HARMONIC ANALYSIS USEFUL FOR DATA SUSPECTED OF CONTAINING OSCILLATORY 

 PHENOMENA. DESIGNED FOR DATA OBTAINABLE ON A REGULARLY SPACED, RECT- 

 ANGULAR GRID. THE PROGRAM COMPUTES COEFFICIENTS OF FOURIER StRIES AND 

 EVALUATES AND PLOTS THE FUNCTION. ALSO COMPUTES AND PLOTS RESIDUAL 

 VALUES. ALLOWS UP TO 71 X 73 GRID POINTS AND UP TO 25TH HARMONIC IN 

 BOTH DIRECTIONS. COMPUTER CONTRIBUTION 29» BY JOHN W. HARBAuGh AND 

 MICHAEL J. SACKIN (JUNE 1968). AN EARLIER PROGRAM WAS DEVELOPED FOR 

 DOUBLE FOURIER SERIES ANALYSIS OF SURFACES WITH IRREGULARLY SPACED 

 DATA. REF. COMPUTER CONTRIBUTION 5, BY W.R. JAMES (1966).

CLUSTER ANALYSIS LANGUAGE - FORTRAN 



COMPUTER - IBM 1800 SYS 

 (COPY ON FILE AT NODC) 



CARRIES OUT A SINGLE LINKAGE CLUSTER ANALYSIS USING DATA IN THE FORM 

 OF AN UPPER TRIANGULAR SIMILARITY MATRIX. OUTPUT — A) SIMILARITY LEV- 

 EL OF CLUSTERING CyClE, B) A LIST OF THE LINKAGES THAT OCCUR Aj THAT 

 SIMILARITY LEVEL. C) AT THE END OF THE CYCLE THE CLUSTER NUMBERS AND A 

 LIST OF THE ENTITIES MAKING UP EACH CLUSTER IS PRINTED. RUN TIME — 

 A MATRIX OF ORDER 60 TOOK APPROXIMATELY 15 MINUTES TO CLUSTER. N.I.O. 

 PROGRAM NO. 166. AUTHOR — M. FASHAM.
