DESCRIPTION

This routine calculates the element-wise reciprocal of a vector, overwiting the input vector with the result.

RETURNS

NO_ERROR on success, and ERROR on failure, with an error message being set. THis routine will fail if any of the element of the input vector is too close to zero.

DISCLAIMER

This software is not adequatedly tested. It is recomended that results are checked independantly where appropriate.
