This means, that the file fdct_wrapping.m is not found in your Matlab path. I guess you have either forgotten to install the required toolbox, or to add it to your path. See:

doc addpath
doc pathtool

fdct_wrapping migth belong to https://www.mathworks.com/matlabcentral/fileexchange/5104-toolbox-wavelets .
