I am using wavedec to discritize my signal using ‘db4’ wavelet.

my X = acceleration vector(9000 x 1)
My X is finite. But I am getting a error that ‘ Error using wavedec Expected X to be finite’
My code :
[a,l] = wavedec(acc,3,’db4′);
approx = appcoef(a,l,’db4′);
[acd1,acd2,acd3] = detcoef(a,l,[1 2 3]);
figure
subplot(4,1,1)
plot(approx)
title(‘Approximation Coefficients’)
subplot(4,1,2)
plot(acd3)
title(‘Level 3 Detail Coefficients’)
subplot(4,1,3)
plot(acd2)
title(‘Level 2 Detail Coefficients’)
subplot(4,1,4)
plot(acd1)
title(‘Level 1 Detail Coefficients’)

please help me. Where I am wrong. I am unable to solve this problem.I am using wavedec to discritize my signal using ‘db4’ wavelet.
