N (input) Length of the sequence to be transformed. N >= 0.
WSAVE (input/output)
On entry, an array of dimension (2N + N/2 + 15) or
greater. SINTI is called once to initialize WSAVE
before calling SINT and need not be called again
between calls to SINT if N and WSAVE remain
unchanged. Thus, subsequent transforms of same
size can be obtained faster than the first since
they do not require initialization of the
workspace.
