IGOR Functions

addToWaveRange

// Add a value to a specific range of points of a wave
Function addToWaveRange(wname, startPoint, endPoint, addition) 
	wave wname
	variable startPoint
	variable endPoint
	variable addition
	variable ii
	
	for ( ii=0; ii< (endPoint-startPoint); ii += 1 )
		wname[startPoint + ii] += addition
	endfor

end

igor-add

// Adds a value to every point in a wave
Function addToWave(wname, amount)
	wave wname
	variable amount
	wname=wname + amount
	return 0
end

igor-normalize

// normalize a wave against its largest value
// possible improvement: create new wave instead of modifying original data
Function normalizeWave(wname)
      wave wname
 
      WaveStats/Q wname
      wname/=V_max
      return 0
end

igor-Normalize1To0

// Normalize a wave to have values between 0 and 1
Function Normalize1To0(wname)
      wave wname
 
      WaveStats/Q wname
      wname=(wname-V_min)/(V_max - V_min)
      return 0
