#### Routine

void VRfScale (double a, const float x[], float y[], int N)

#### Purpose

Multiply each element of a float array by a scalar value

#### Description

This routine multiplies each element of a float array by a scalar value,

      y[i] = a * x[i],  0 <= i < N.

#### Parameters

-> double a
  A scalar value
-> const float x[]
