Error: Undefined variable cwtplot in Scilab

I try to analyze 3-d image of the wavelet transform of the signal (image is obtained using the mesh function) Then I want to get my 2-d image of the wavelet transform using the cwtplot function.

cwtplot(signal, 1:32)

However, scilab shows an error

Undefined variable cwtplot
Solution

  • I created a new version 0.3.2 of the Atoms module "Scilab Wavelet Toolbox". It was just a matter of recompilation (+some other small fixes). If you update the Atoms database you should be able to download it:

    --> atomsSystemUpdate
--> atomsInstall swt
--> atomsLoad swt

 Start swt toolbox - (0.3.2)
    Load macros
    Load gateways
    Load help
    Load demos

    The page of the updated Atoms is there: https://atoms.scilab.org/toolboxes/swt/0.3.2 and here is a screenshoft of the cwtplot help page example:
