I am trying to use haart2 in matlab , but everytime it shows me this error
Undefined function or variable 'haart2'.
Error in haar (line 5)
[a2,h2,v2,d2] = haart2(im,2);
So i checked if i have the wavelet toolbox and it turns out that it exists in my matlab :
>> ver wavelet

dwtmode('per');
[CA,CH,CV,CD] = dwt2(X,'haar');
I am not sure if the dwtmode() is needed; I am copying from an old posting.

So far as I can see the function in the Wavelet Toolbox is named
haart
so I'm not sure what your haar function is, but it isn't the one from the toolbox unless it is an old version.
