resample - resample numeric columns in a table

SYNOPSYS

    resample controltable keycol[:controlkeycol] col1 ... [coln] [< input]

resampletable is used to resample numeric columns in a table to a set of points specified by a column in a control table. The resampling is done using linear interpolation. Both tables must be sorted on the key column before calling this program. The keycol and col1...coln are written to the output. The number of rows in the output table is equal to the number of rows in the control table. If the control value is outside the range of the key values in the input file, the output value is linearly extrapolated using the end values.

OPTIONS

• controltable - The name of the table that will control the resampling

• keycol - The name of the column in the input table that specifies the original ordinate values.

• controlkeycol - The name of the column in the control table that is used to specify the new ordinate values. If controlkeycol is not specified it is assumed to be the same as keycol.

• col ... - Names of columns in the input table that will be resampled.
