INTERPX

Name


      INTERPX

Purpose


      Interpolate data with possible gaps and missing (bad) values.

Category


Calling Sequence


      yy = interp1(x,y,xx)

Inputs


      x,y = input points. in
        x is assumed monotonically increasing.
      xx = desired x values. in
        xx need not be monotonically increasing.

Keyword Parameters


Keywords


        BAD=b Values GREATER THAN b are considered missing.
        GAP=g Gaps in x greater than or equal to this
          are broken by setting the output curve points
          in the gaps to a flag value of 32000 or BAD if given.
        /FIXBAD means interpolate across bad data between
          closest good points on each side. Otherwise the
          bad points are flagged with the value specified
          for BAD.

Outputs


      yy = interpolated y values. out

Common Blocks


Notes


      Notes: Flagged values may be used to break a plotted
          curve using MAX_VALUE in the PLOT or OPLOT command:
          plot,x,y,max_value=999
          SLOW for more than a few thousand points.
