Examples

1. To perform wavelet smoothing using default settings, to XY data in columns 1, 2 of the active worksheet, by cutting off 90% of the detail coefficients, use the script command:

wtsmooth iy:=(Col(1),Col(2)) cutoff:=90

2. To perform default wavelet smoothing to active data plot in graph, activate the plot then use the script command:

wtsmooth %c

3. To perform wavelet smoothing to data using a pre-saved smoothing theme file called Mytheme type in the Command Window:

wtsmooth -t mytheme
