- function x = HardTh(y,thld)
- % x = HardTh(y,thld);
- %
- % HARDTH hard thresholds the input signal y with the threshold value
- % thld.
- %
- % Input:
- % y : 1D or 2D signal to be thresholded
- % thld : threshold value
- %
- % Output:
- % x : Hard thresholded output (x = (abs(y)>thld).*y)
- %
- % HERE'S AN EASY WAY TO RUN THE EXAMPLES:
- % Cut-and-paste the example you want to run to a new file
- % called ex.m, for example. Delete out the % at the beginning
- % of each line in ex.m (Can use search-and-replace in your editor
- % to replace it with a space). Type 'ex' in matlab and hit return.
- %
- %
- % Example:
- % y = makesig('WernerSorrows',8);
- % thld = 1;
- % x = HardTh(y,thld)
- % x = 1.5545 5.3175 0 1.6956 -1.2678 0 1.7332 0
