- These routines are part of the SCSL Scientific Library and can be loaded
- using either the -lscs or the -lscs_mp option. The -lscs_mp option
- directs the linker to use the multi-processor version of the library.
-
- When linking to SCSL with -lscs or -lscs_mp, the default integer size is
- 4 bytes (32 bits). Another version of SCSL is available in which integers
- are 8 bytes (64 bits). This version allows the user access to larger
- memory sizes and helps when porting legacy Cray codes. It can be loaded
- by using the -lscs_i8 option or the -lscs_i8_mp option. A program may use
- only one of the two versions; 4-byte integer and 8-byte integer library
- calls cannot be mixed.

- CLARTV applies a vector of complex plane rotations with real cosines to
- elements of the complex vectors x and y. For i = 1,2,...,n
- ( x(i) ) := ( c(i) s(i) ) ( x(i) )
- ( y(i) ) ( -conjg(s(i)) c(i) ) ( y(i) )
-
-
- AAAARRRRGGGGUUUUMMMMEEEENNNNTTTTSSSS
- N (input) INTEGER
- The number of plane rotations to be applied.
-
- X (input/output) COMPLEX array, dimension (1+(N-1)*INCX)
- The vector x.
-
- INCX (input) INTEGER
- The increment between elements of X. INCX > 0.
-
- Y (input/output) COMPLEX array, dimension (1+(N-1)*INCY)
- The vector y.
-
- INCY (input) INTEGER
- The increment between elements of Y. INCY > 0.
-
- C (input) REAL array, dimension (1+(N-1)*INCC)
- The cosines of the plane rotations.
