I am looking for a software that can compute the following integral
$∫_0^1f(x)\phi(2^jx-k)dx.$

$\phi(x)$ is scaling function of a wavelet family (especially Daubechies), j and k are scaling and translation parameters respectively.

Basically any software that can do numerics for you, e.g. Wolfram Mathematica, Matlab, or you can write a C code as well (using GSL).

If you can use this
http://reference.wolfram.com/mathematica/guide/Wavelets.html
to translate what you are interested in into one or two simple concrete examples then we can try it and see if the results will be in a form you can use.
