db2.mat missing?

Question

0 个投票

Hello,

I'm trying to perform a wavelet analysis using a downloaded script - the script uses the db2.mat variable which is supposedly part of the wavelet toolbox. I have the toolbox installed and activated in MATLAB, located at 'C:\Program Files\MATLAB\R2018a\toolbox\wavelet'

The script throws an error saying: 'Function hmrMotionCorrectWavelet generated ERROR at line 59: Unable to read file '/db2.mat'. No

such file or directory.'

When I search for the file within the wavelet toolbox folder it gives no results. I am using 2018a. Any help would be appreciated.

Where did you get the script from? Which version of MATLAB was that script written for? It coud be that it was written for an older version of MATLAB (or the toolbox) where the db2.mat file existed....or it could be that this file is supposed to be included with the script you downloaded.
