This will generate random data that is timestamped in a CSV

RandomNumberSet.rb

#! ruby

# This will generate a negative number set that i can use for testing my compression analysis
# 
# Example:
#   NegNumSet numberOfPoints [max] [freq]
#
# Arguments (all are optional so far):
#   1: numberOfPoints - the number of points to generate
#   2: Max - the maximum distance from zero that the data point values can have
#   3: Freq - the maximum distance in seconds between each point

if ARGV[0]
  numberOfPoints = ARGV[0].to_i
else
  numberOfPoints = 10
end

if ARGV[1]
  max = ARGV[1].to_f
else
  max = 10.0
end

if ARGV[2]
  freq = ARGV[2].to_f
else
  freq = 0.5
end

puts "Generated data"

random = Random.new
timestamp = Time.now

(0..numberOfPoints).each do
  timestamp = timestamp + random.rand( freq )
  data = random.rand( max )

  # Generate the sign for the number randomly
  sign = random.rand()
  if sign < 0.5
    data = -data
  end

  # Output our random generated data set
  puts "#{timestamp.strftime("%m/%d/%Y %H:%M:%S.%3N")},#{data.to_s}\n"
end
