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 |
    a
    i
    | < |
    b
    i
    |
    v?MaxMag
    returns
    a
    i
    , otherwise
    v?MaxMag
    returns
    a
    i
    .
  • If |
    b
    i
    | < |
    a
    i
    |
    v?MaxMag
    returns
    b
    i
    , otherwise
    v?MaxMag
    returns
    a
    i
    .
  • Otherwise
    v?MaxMag
    behaves like
    v?Fmin
    .
