1. To decompose the 1st matrix object in the 1st sheet of MBook1 using DB2 wavelet and save the result to different matrices, use the following script command:
dwt2 im:=[MBook1]1!Mat(1) type:=1 ca:=[MBook2]1!Mat(1) ch:= [MBook2]2!Mat(1) cv:= [MBook2]3!Mat(1) cd:= [MBook5]1!Mat(1);
2. To open the dwt2 dialog, use the script command:
dwt2 -d
3. To perform dwt2 to data using a pre-saved analysis theme file, save your preferences in the advanced options in the dwt2 dialog, and then execute it by typing (for example, but using your own saved-theme title) the script command:
dwt2 -t "my theme.oth"
