WebIf it is a vector, you can use pywavelets (forward DWT, truncation, backward DWT). If it is an expression, you may want to sample it and use pywavelets. This will give you an idea of how well the approximation will be. You can also implement the expansion into the (truncated) Haar basis by yourself using numerical or symbolic integration.
