def	curverat
	--latex This approach is based on rescaling the weighting vectors ( $w_{1}$ or $w_{2}$ ) in such a way that after the application of the rescaled vectors for soft thresholding a certain percentage (the n relatively largest coefficients) remain in the thresholded vector per scale or globally.

	)

--latex This approach is based on rescaling the weighting vectors ( $w_{1}$ or $w_{2}$ ) in such a way that after the application of the rescaled vectors for soft thresholding a certain percentage (the n relatively largest coefficients) remain in the thresholded vector per scale or globally.

The operation is based on the following steps: \begin{enumerate} \item Initialize a vector of the size of the to be thresholded and thresholding vector \item Calculate the ratio ( rat = curvec1 / curvec2 ) over the total vector. \item Sort rat in descending order to evaluate for the coefficients mainly con- tributing to curvec1 \item Take the value of the sorted rat vector defined by an initial percentage of values you want to keep cutv. \end{enumerate}
