FunctionFind the largest deviation between the elements of a vector and a reference value.

function cusdVF_maxreldevC( d_RetVal:PSingle; d_X:fVector; size:UIntSize; d_C:PSingle ): IntBool;

DescriptionThe relative deviation (in absolute terms) of each element of a vector X from a reference value C is calculated as
reldev = |Xi − C|  /  |C|
and the largest reldev encountered is returned.

The reference value C=0 is not allowed, as it would lead to a division by zero.

Error handlingnone
Return valuemaximum relative deviation encountered.
