WaveMinAndMax

WaveMinAndMax (wave [, x1, x2])

The WaveMinAndMax function returns the minimum and maximum values in the wave for points between x=x1 to x=x2, inclusive.

WaveMinAndMax must be called from a function, not from the command line, because it uses multiple return syntax as shown in the example below.

WaveMinAndMax was added in Igor Pro 9.00.

Details

If x1 and x2 are omitted, they default to -inf and +inf.

The X scaling of the wave is used only to locate the points nearest to x=x1 and x=x2. To use point indexing, replace x1 with "pnt2x(wave,pointNumber1)", and a similar expression for x2. The resulting point numbers are clipped to the range 0..n where n is the numpnts(wave )-1.

NaN values in the wave are ignored.

Example

Function DemoWaveMinAndMax()
	Make/FREE wave0 = p
	wave0[0] = NaN	// NaN values are ignored
	SetScale/P x, 0, 0.1, "s", wave0
	double minValue, maxValue
	
	[minValue, maxValue] = WaveMinAndMax(wave0)
	Printf "Entire wave: min=%g, max=%g\r", minValue, maxValue

	[minValue, maxValue] = WaveMinAndMax(wave0, 5, 10)
	Printf "From x=5 to x=10: min=%g, max=%g\r", minValue, maxValue
End
