[Sc-devel] maxIndex and minIndex?

[Click Nilson <clicksonnil@xxxxxxxxx>]

Just wondering whether there is a method already for returning the  
index of the maximum or minimum element (rather than the value)? This  
is something I've often been recoding in algorithms and added my own  
extentions to SequenceableCollection as below; but perhaps there is  
some existing method I don't know the name of? Else can I add these?  
I have an interpolation constructor method as well that could go in  
as a convenience method rather than .series...

best,
Nick


+ SequenceableCollection {
*interp { arg size, start=0.0, end=1.0;
		var obj = this.new(size);
		
		if(size!=1,{
		size.do {|i|
		var t;
		
			t= i/(size-1);
			
			obj.add(start + (t*(end-start)));
		};
		},{obj.add(start);});
		
		^obj
}
maxIndex {

	var maxValue, maxElement, maxIndex;
			this.do { | elem,index|
				if (maxElement.isNil) {
					maxElement = elem;
					maxIndex = index;
				}{
					if (elem > maxElement) {
						maxElement = elem;
						maxIndex = index;
					}
				}		
			}
			^maxIndex;
}



minIndex {

	var minValue, minElement, minIndex;
			this.do { | elem,index|
				if (minElement.isNil) {
					minElement = elem;
					minIndex = index;
				}{
					if (elem < minElement) {
						minElement = elem;
						minIndex = index;
					}
				}		
			}
			^minIndex;
}
