dawn@0 1 % [y,idx] = minparabolic(x) - locate minima using parabolic interpolation
dawn@0 2 %
dawn@0 3 % x: input vector
dawn@0 4 % y: same as x, with local minima replaced by interpolated minima
dawn@0 5 % idx: position of interpolated minima (fractionary)
dawn@0 6 %
dawn@0 7 % At each local minimum of x, that sample and its neighbors are used to
dawn@0 8 % determine a parabola. The minimum of the parabola is used as the new
dawn@0 9 % minimum value, the abscissa of the minimum is used as its position.
