vsinqb (3p)

Name

vsinqb - synthesize a Fourier sequence from its representation in terms of a sine series with odd wave numbers. The VSINQ operations are nor- malized, so a call of VSINQF followed by a call of VSINQB will return the original sequence.

       of a sine series with odd wave numbers.  The VSINQ operations are  nor-
       malized,  so  a call of VSINQF followed by a call of VSINQB will return

ARGUMENTS
       M (input)
                 The number of sequences to be transformed.  M >= 0.


       N (input) Length of the sequence to be transformed.  These  subroutines
                 are most efficient when N is a product of small primes.  N >=
                 0.


       X (input/output)
                 On entry, a real two- dimensional array  with  dimensions  of
                 (MDIMX  x  N)  whose  rows contain the sequences to be trans-
                 formed.  On exit, the  quarter-wave  sine  synthesis  of  the
                 input.


       XT (input)
                 A real two-dimensional work array with dimensions of (MDIMX x
                 N).


       MDIMX (input)
                 Leading dimension of the arrays X and XT as  specified  in  a
                 dimension or type statement.  MDIMX >= M.


       WSAVE (input)
                 On  entry,  an  array with dimension of at least (2 * N + 15)
                 for vector subroutines, initialized by VSINQI.
