Examples
1. To reconstruct a 2D matrix from 4 matrix objects in the active matrix layer, use the script command:
idwt2 ca:=mat(1) ch:=mat(2) cv:=mat(3) cd:=mat(4);
2. To open the idwt2 dialog, use the script command:
idwt2 -d;
3. To perform idwt2 to data using a pre-saved analysis theme file, save your preferences in the advanced options in the idwt2 dialog, and then execute it by typing (for example, but using your own saved-theme title) the script command:
idwt2 -t "my theme.oth"
