CSAMPLE Instruction

CSAMPLE( options ) cseries start end newcseries newstart

CSAMPLE selects entries from a complex series to reduce the number of ordinates. It creates newcseries by selecting only one entry per sampling interval from cseries. The CPRINT and CTOR instructions have built-in options which accomplish much the same thing.

Parameters

cseries	source series
start, end	range to transform, by default, range of cseries
newcseries	result series, by default, overwrites cseries
newcstart	start for newcseries, by default, start

Options

INTERVAL=sampling interval [1]

This is the width of the sampling interval.

Example

freq 5 384

...

csample(interval=3) 1 1 384 2

Series 2 is set equal to entries 1,4,7,... from series 1.
