MATLAB: The loop is not running

loopMATLABwavelet

The code (given below) has been made to run loop for a series of wavelets in 'ufwt' function. When I am running the code, it is showing error; but when i am using a specific wavelet replacing 'a', then the code is running. Kindly help.
the code as follows:
wt = ["db2";"db4";"db6";"db8";"db10"];
for i=1:5
a = wt(i) % Selection of wavelet according to the run number
[c,info] = ufwt(s,a,1);
snent(i) = wentropy(c(1),'shannon');
end
