Quantlet: | softauto | |
Description: | Softthresholds the mother wavelet coefficients b1 and b2 automatically by sqrt(2 sigma n). To compute the threshold value only b1 and x is used. |
Usage: | {bn1, bn2} = softauto (b1, b2, x) | |
Input: | ||
b1 | n x 3 array of mother wavelet coefficient | |
b2 | n x 3 array of mother wavelet coefficient | |
x | m x 1 array of data | |
Output: | ||
bn1 | n x 3 array of thresholded mother wavelet coefficient | |
bn2 | n x 3 array of thresholded mother wavelet coefficient |
