Non-zero set
The nonzero set is a mathematical term used to describe the complement of the set of zeros.
Zeros are those variable values of a (mathematical) function which, when inserted into this function, yield the function value zero . The set of zeros thus describes the set of variables that result in the function value zero .
The set of all variables of a function that do not result in the function value zero is called the non- zero set . The non-zero set has numerous applications in mathematics and technology .
