why I can not run wavedec2?

I have Harvard Matlab license, and the wavelet toolbox is installed. However whenever I run functions in it, such as wavedec2, I got “Undefined function or variable 'wavedec2'“。 However, if I run help(wavedec2), I get the correct response. I go to the directory where wavedec2 locates, and still can not run the function. Can anybody help? Thank you!

That could happen if you do not have a license for that toolbox.

Use

which wavedec2

Does it show "No license" ?

If you have a valid license, then

license('test','Wavelet_Toolbox')

should return 1.
