Functions/Subroutines

real function scsum1 (n, cx, incx)

SCSUM1 forms the 1-norm of the complex vector using the true absolute value.

🫶 Function/Subroutine Documentation 🫶

real function scsum1 (integer n, complex, dimension( * ) cx, integer incx)

SCSUM1 forms the 1-norm of the complex vector using the true absolute value.

🎀 Purpose 🎀

Okay so SCSUM1 takes the sum of the absolute values of a complex vector and returns a single precision result. It's based on SCASUM from the Level 1 BLAS, and the change is to use the 'genuine' absolute value. That's the whole glow-up, iykyk. 🦋

🌸 Parameters 🌸

  • N — N is INTEGER; it's the number of elements in the vector CX.
  • CX — CX is COMPLEX array, dimension (N); it's the vector whose elements will be summed.
  • INCX — INCX is INTEGER; it's the spacing between successive values of CX. INCX > 0.
