wcodemat and uint8 error

I am getting the following while trying to run my code. Could anyone explain the reason?

Undefined function 'wcodemat' for input arguments of type 'uint8'

What this error message is telling you is that the function wcodemat, which you are using somewhere in your code, is not defined (or not found). This function is part of the Wavelet Toolbox. Have you installed this toolbox?

In the Command Window type the following

 which wcodemat
 ver

The first command will try to locate this function. I don't have this toolbox so the function returns

 'wcodemat' not found.

ver will return version information for your MATLAB and list all toolboxes that have been installed. Check to see if the Wavelet Toolbox is in that list.

Thank you very much Geoff for the answer. I don't have it installed. I just downloaded the toolbox from the following link(<http://www.mathworks.com/matlabcentral/fileexchange/5104-toolbox-wavelets>) but not sure how to use it. Do you know how can I use the toolbox?

Thanks Faruk

Hi Faruk - no, I don't know how to use this package. Note that it is NOT the The Mathworks Wavelet Toolbox, so it may not have the wcodemat that you are expecting.

Ok. Thank you. I hope I will find the right package. :)
