Minimum absolute value and location F_SAMIN_VAL/F_DAMIN_VAL/F_CAMIN_VAL/F_ZAMIN_VAL
Name F_SAMIN_VAL/F_DAMIN_VAL/F_CAMIN_VAL/F_ZAMIN_VAL
Minimum absolute value and location
Purpose F_xAMIN_VAL returns the smallest component of the vector x with respect to
the absolute value and also returns the offset or index of the smallest
component of the vector x. When the value of the n argument is less than or
equal to zero, the routine should initialize the output scalars k to the largest
invalid index (zero), and r to zero. The resulting scalar r is always real.
