The rest of the proof of Theorem 5.1 is a fairly straightforward woozle-hunt (Milne )
lcrp — calculate the Lipschitz constant k(p) for the projection onto the unit ball of p-norm function and sequence spaces.
|double * C
lcrp function takes an double
p (which should be between one and
INFINITY inclusive) and assigns the Lipschitz constant k(p) to the
double whose address is given by the parameter
On success, the function returns zero (
LCRP_OK) and assigns
On failure, the function returns a non-zero value and does not assign
C. The return value can be passed to the function
lcrp_strerror to obtain a description of the error.
