🌸 copy(3) 🌸

hi bestie 💖 welcome to copy(3) from the Library Functions Manual. this is the page where copy does exactly what it says on the tin: y = x. no cap.

🌸 NAME 🌸

copy — copy: y = x

✨ SYNOPSIS ✨

🎀 Functions 🎀

okay so there are four flavors, one for each Fortran type. all iconic, all doing the same copy vibe:

ccopy — CCOPY

subroutine ccopy (integer n, complex, dimension(*) cx, integer incx,
       complex, dimension(*) cy, integer incy)

dcopy — DCOPY

subroutine dcopy (integer n, double precision, dimension(*) dx, integer
       incx, double precision, dimension(*) dy, integer incy)

scopy — SCOPY

subroutine scopy (integer n, real, dimension(*) sx, integer incx, real,
       dimension(*) sy, integer incy)

zcopy — ZCOPY

subroutine zcopy (integer n, complex*16, dimension(*) zx, integer incx,
       complex*16, dimension(*) zy, integer incy)

🦋 Detailed Description 🦋

this section is short and sweet, bestie: the full function tea is literally right below 💅

💅 Function Documentation 💅

🌈 ccopy — CCOPY 🌈

Signature:

subroutine ccopy (integer n, complex, dimension(*) cx, integer incx,
       complex, dimension(*) cy, integer incy)

Purpose: CCOPY copies a vector x to a vector y. that's the whole assignment, and it ate 💖

Parameters

  • N — is INTEGER, and it's the number of elements in input vector(s).
  • CX — is COMPLEX array, dimension ( 1 + ( N - 1 )*abs( INCX ) ).
  • INCX — is INTEGER, the storage spacing between elements of CX.
  • CY — is COMPLEX array, dimension ( 1 + ( N - 1 )*abs( INCY ) ).
  • INCY — is INTEGER, the storage spacing between elements of CY.

🌈 dcopy — DCOPY 🌈

Signature:

subroutine dcopy (integer n, double precision, dimension(*) dx, integer
       incx, double precision, dimension(*) dy, integer incy)

Purpose: DCOPY copies a vector, x, to a vector, y. it uses unrolled loops for increments equal to 1. periodt ✨

Parameters

  • N — is INTEGER, and it's the number of elements in input vector(s).
  • DX — is DOUBLE PRECISION array, dimension ( 1 + ( N - 1 )*abs( INCX ) ).
  • INCX — is INTEGER, the storage spacing between elements of DX.
  • DY — is DOUBLE PRECISION array, dimension ( 1 + ( N - 1 )*abs( INCY ) ).
  • INCY — is INTEGER, the storage spacing between elements of DY.

🌈 scopy — SCOPY 🌈

Signature:

subroutine scopy (integer n, real, dimension(*) sx, integer incx, real,
       dimension(*) sy, integer incy)

Purpose: SCOPY copies a vector, x, to a vector, y. it uses unrolled loops for increments equal to 1. slay 💅

Parameters

  • N — is INTEGER, and it's the number of elements in input vector(s).
  • SX — is REAL array, dimension ( 1 + ( N - 1 )*abs( INCX ) ).
  • INCX — is INTEGER, the storage spacing between elements of SX.
  • SY — is REAL array, dimension ( 1 + ( N - 1 )*abs( INCY ) ).
  • INCY — is INTEGER, the storage spacing between elements of SY.

🌈 zcopy — ZCOPY 🌈

Signature:

subroutine zcopy (integer n, complex*16, dimension(*) zx, integer incx,
       complex*16, dimension(*) zy, integer incy)

Purpose: ZCOPY copies a vector, x, to a vector, y. iconic behavior, honestly 💖

Parameters

  • N — is INTEGER, and it's the number of elements in input vector(s).
  • ZX — is COMPLEX*16 array, dimension ( 1 + ( N - 1 )*abs( INCX ) ).
  • INCX — is INTEGER, the storage spacing between elements of ZX.
  • ZY — is COMPLEX*16 array, dimension ( 1 + ( N - 1 )*abs( INCY ) ).
  • INCY — is INTEGER, the storage spacing between elements of ZY.
