Description

y

REAL for vsminmag

REAL for vmsminmag

DOUBLE PRECISION for vdminmag

DOUBLE PRECISION for vmdminmagjjssd

Pointer to an array containing the output vector y.

Description

The v?MinMag function returns a vector with element values equal to the element with the smaller magnitude from each pair of corresponding elements of the two vectors a and b:

  • If |ai| < |bi| v?MaxMag returns ai, otherwise v?MaxMag returns ai.

  • If |bi| < |ai| v?MaxMag returns bi, otherwise v?MaxMag returns ai.

  • Otherwise v?MaxMag behaves like v?Fmin.
