      Useful MAXIMA User's Functions                     (used to process the transfer functions produced by the schematic editor) 
  
  
  

      HILO(xfer)                 HILO(XFER[3])               return a transfer function after applying limits to HIxx.. and LOyy.. 
  
          Elements named with a prefix HI.. (like HI, HI1, HIr, HIc13, etc) are processed as an infinite value 
          Elements named with a perfix LO.. (like LO, LO9, LOr, LOc0,  etc) are processed as a zero value 
  
      NUMERIC(xfer)              NUMERIC(XFER[2])            return a transfer function after inserting numerical values if any 
      SUBSTITUTE(xfer,parm,val)  SUBSTITUTE(XFER[1],gds1,gn) return a transfer function after substitution 
  
      NUMERATOR(xfr)             NUMERATOR(XFER[1])          return the numerator of a transfer function 
      DENOMINATOR(xfr)           DENOMINATOR(XFER[3])        return the denominator of a transfer function 
  
      NCOEFF(xfer,n)             NCOEFF(XFER[2],2)           return the nth coefficient of the numerator of a transfer function 
      DCOEFF(xfer,n)             DCOEFF(XFER[1],3)           return the nth coefficient of the denominator of a transfer function 
  
      DC(xfer)                   DC(XFER[1])                 return the DC transfer function 
      INF(xfer)                  INF(XFER[1])                return the transfer function at infinite frequency 
  
      NUMFORM(num,n)             NUMFORM(17,-4)              format a number, return string "0017",  sign of num is suppressed 
                                 NUMFORM(17, 4)              format a number, return string "17  ",  sign of num is suppressed 
  
  
      Useful to signal the end of the processing which could be in some cases (very) long 
  
      DONE( )                                                print a line "end of the processing" 
      SMAKE( )                                               protected smake against negative value
