4.82 sddspoly

• description: sddspoly evaluates polynomials for N-dimensional input.
• examples:
    sddspoly <inputfile> <outputfile> -evaluate=filename=<polyFilename>,output=y,coefficients=coef,input0=x,power0=power  
      

• synopsis:
    sddspoly [inputfile] [outputfile] [-pipe=[input][,output]]  
      -evaluate=filename=polyFilename,output=column,coefficients=column,  
      input0=inputColumn,power0=powerColumn  
      [input1=inputColumn,power1=powerColumn][,...]  
      [-evaluate=...]  
      

• files: The input file contains the inputColumns. The polynomial file contains the coefficient column as well as the powerColumns. The output file contains the inputColumns and evaluated output columns.
• switches:
  • -pipe=[input][,output] — Standard SDDS pipe options for reading or writing files from stdin or stdout.
  • -evaluate=... — Specifies evaluation of polynomial, specified in file polyFilename. The results of the evaluation are in the outputfile under the name given with output=column. The polynomial coefficients are in the column named with coefficients=column. The input<n> qualifiers give the names of columns in inputfile that are inputs to the polynomial. The power<n> qualifiers give the names of columns in the polyFilename file that give the powers of the input<n> columns to use for each coefficient.
