function RMS: Double;
Root mean squared of all non-zero elements.
Returns: Double
Examples
var a: Matrix;
c: double;
begin
a.SetIt(1,4,False,[1,2,3,4]);
c := a.RMS;
end;var
a: Matrix;
result: double;
begin
a := [[1.0, 2.0], [3.0, 4.0]];
result := a.RMS;
if Abs(result - 2.73861278752583) > 1e-10 then
raise Exception.Create('Matrix.RMS: expected 2.73861278752583, got ' + result.ToString);
end;Indexed: function RMS(Index: Integer; Len: Integer): Double;
Calculate the RMS for calling object elements [Index]..[Index+Len-1] in-place.
