wavelets to interval [0,1]
) to improve numerical stability.
In light of the remark (
some of the

We discard such functions and obtain the basis to match the
the obtained functions.
The procedure is implemented in the script "bases\psi.py" and tested by the
script "_run_bases.py". The flat version (no classes) of the procedure may be
found in the file tApprox.py. The same file performs various tests. In
particular, we verify directly that we have the scaling relationship and low
condition numbers for various Gram matrixes.
