vdsinqf (3p)

Name

vdsinqf - tion with only odd wave numbers. The VSINQ operations are normalized, so a call of VSINQF followed by a call of VSINQB will return the origi- nal sequence.

NAME
       vdsinqf - compute the Fourier coefficients in a sine series representa-
       tion with only odd wave numbers.  The VSINQ operations are  normalized,
       so a call of VSINQF followed by a call of VSINQB will return the origi-
       nal sequence.

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, an array of length N containing the sequence to  be
                 transformed.   For  VSINQF, a real two-dimensional array with
                 dimensions of (MDIMX x N) whose rows contain the sequences to
                 be  transformed.  On exit, the quarter-wave sine transform 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),
                 initialized by VSINQI.
