Description

y

REAL for vsfmax

REAL for vmsfmax

DOUBLE PRECISION for vdfmax

DOUBLE PRECISION for vmdfmaxjjssd

Pointer to an array containing the output vector y.

Description

The v?Fmax function returns a vector with element values equal to the larger value from each pair of corresponding elements of the two vectors a and b: if ai < biv?Fmax returns bi, otherwise v?Fmax returns ai.
