SRC/clacrt.f(3)

💅 NAME 💅

SRC/clacrt.f — okay so this is the page for that routine, bestie. The manual name is Library Functions Manual, and the whole vibe is “tiny file, big complex-vector transformation energy.” ✨

✨ SYNOPSIS ✨

Functions/Subroutines

• subroutine clacrt (n, cx, incx, cy, incy, c, s) — CLACRT performs a linear transformation of a pair of complex vectors. Periodt. 💅

🦋 Function/Subroutine Documentation 🦋

subroutine clacrt (integer n, complex, dimension( * ) cx, integer incx,
    complex, dimension( * ) cy, integer incy, complex c, complex s)

CLACRT performs a linear transformation of a pair of complex vectors. No cap. 🫶

🎀 Purpose 🎀

okay so CLACRT performs the operation

   (  c  s )( x )  ==> ( x )
   ( -s  c )( y )      ( y )

where c and s are complex and the vectors x and y are complex. Iconic behavior, honestly. 🌸

🌸 Parameters 🌸

• N — is INTEGER. The number of elements in the vectors CX and CY.
• CX — is COMPLEX array, dimension (N). On input, the vector x. On output, CX is overwritten with c*x + s*y.
• INCX — is INTEGER. The increment between successive values of CX. INCX <> 0.
• CY — is COMPLEX array, dimension (N). On input, the vector y. On output, CY is overwritten with -s*x + c*y.
• INCY — is INTEGER. The increment between successive values of CY. INCY <> 0.
• C — is COMPLEX.
• S — is COMPLEX. C and S define the matrix

   [  C   S  ].
   [ -S   C  ]
