Description

Computes the fms:

Parameters

i1_first, i1_last

The first range of input elements

i2

The beggining of the the second range of input elements

i3

The beggining of the the third range of input elements

o0

The beginning of the destination range, may be equal to i1 or i2

i1, i2, i3

The scalar/contiguous data input elements
