image2=('C:\Users\hp\Desktop\data\1 (1).JPG');
[h l]= newwavelet(image2)
WAVEMNGR('add','shivjoshi','josh',1,'','newwavelet')
OUT1 = WAVEMNGR('read')
[C,S] = wavedec2(image2,2,'josh');
here in 2nd line h and l have high and low pass coefficients the code is working upto 4th line when i use OUT1 = WAVEMNGR('read') my new added wavelet is showing but in the 5th line error occured that file 'josh' doesnt exist

You should have an M-file that just defines the scaling filter for an orthogonal wavelet
So for example:
function h = newwavelet(wname)
h = [-0.0106
0.0329
0.0308
-0.1870
-0.0280
0.6309
0.7148
0.2304];
end
Then, first delete what you have already done.
wavemngr('del','josh');
Then, re-add
wavemngr('add','shivjoshi','josh',1,'','newwavelet.m')
Next, check that the wavelet is there
wavemngr('read')
Finally, create some data to test
Im = randn(10,10);
[C,S] = wavedec2(Im,1,'josh');

why are you inputting image2 into newwavelet? You do NOT input the image data into newwavelet.m. newwavelet.m should take only one input argument and that input argument should be wname. Just like I have done above in my example. MATLAB will call newwavelet.m with
newwavelet('josh')
and that should return a 1-D vector that is the scaling filter.
So if your newwavelet.m function does not work with:
h = newwavelet('josh');
then you are doing it wrong.
