int
idamin (int n, const double *x, int incx)

finds the smallest index of the minimum magnitude element of double-
precision vector x; that is, the result is the first i, i = 0 to n - 1,
that minimizes abs(x[1 + i * incx])).

Input
-----
n      number of elements in input vector
x      double-precision vector with n elements
incx   storage spacing between elements of x

Output
------
returns the smallest index (0 if n <= 0 or incx <= 0)
